9800x3d vs 7800x3d - 30% price difference, is 10% performance worth it
Posted by ravanlike@reddit | buildapc | View on Reddit | 117 comments
Hi all,
I'm moving from AM4 platform to AM5, currently have 5700x3d + rx6900xt, playing 1440p on 240hz display.
I was thinking about moving after I get 5080S or 5070tiS, but it looks I have to move earlier, so initially thought about simply getting 9800x3d but I've noticed that on my local market, price gap between 7800x3d is way bigger (560 usd for 9800x3d, 430 usd for 7800x3d, so around 30% pay more) than performance difference (at average 10%).
So what would you do? get 7800x3d as it's more reasonable, or screw it and get 9800x3d?
In both cases it would be limited by GPU, until I change it in few months.
After change 9800x3d should have a lead.
AD1SAN0@reddit
Difference between 9800X3D and 7800X3D in 1440p is... 3% with 4090 (would be MUCH lower with 5070 TI - about the same as 4090 in 4K - 0.3 FPS difference). No point in spending $80 on that.
blackholes__@reddit
if you bundle at MC it's only like a $50 difference
e0nflux@reddit
Be aware microcenter has a 2 week return window. My asus mb took a shit at 3 weeks which required me to send it back to asus via rma.
sk3tchcom@reddit
Did you try to return it at MC, anyway? They’re usually SUPER cool about that type of stuff. If not - future folks reading this - try. Worst ANY store can do is say no.
e0nflux@reddit
So here's my dilemma, microcenter is an hour from me, I tried to call, but couldn't get through to a real human or the direct store itself. I didn't want to be in the position of driving 2 hrs plus traffic so potentially 3 or 4 hours driving only for them to deny me. I tried to find Info online , which Indictated they wouldn't work with me. So I decided to send back to asus
HiCustodian1@reddit
Yeah they’ve been nothing but extremely chill in my experience. Brother bought one of their house brand Powerspec pcs from them (on my recommendation) years ago, it wasn’t posting out of the box, and instead of making him jump through hoops they just gave him a new unit that they tested in store that day and took the old one back.
I’m sure there’s a dickhead manager or two that would give you trouble, but for the most part I think you’re in pretty good hands at MC.
Roo529@reddit
MC let me return a 9070 XT after 3 months 🙂
Tiffany-X@reddit
Which model motherboard? Just so I can avoid. Was it a PRIME
e0nflux@reddit
Yeah the cheaper one.
HiCustodian1@reddit
Eh I mean it would be a stupid upgrade but it would be higher than that with settings people would actually use. Most people gonna be using DLSS quality, it usually looks better than native TAA. Gap starts to widen at that point, you’d be rendering at less than 1080p internally.
Again, it’d be an insane upgrade, but if you’re building a new system it’s not totally idiotic.
ye1l@reddit
Averages are pointless for this discussion, it's far more important to know what games OP is playing.
In a lot of modern singleplayer games a 5700x3d will perform just as well as a 9800x3d while in CS2 for example, a 9800x3d will show 1% and 0.1% lows almost 20% higher than a even a 7800x3d which matters a whole lot more than your average fps. Recommending him one or the other without knowing what games he's playing is like Recommending car parts to someone when you don't even know what car they drive.
cbusmatty@reddit
What about world of Warcraft? This is where I am at. It’s massively cpu bound, my gfx card doesn’t even spike at all, but my cpu is bottoming
ye1l@reddit
Your average fps will see a nice >20% bump comparing a 7800x3d and a 9800x3d, however, in very demanding scenario like a complete meat grinder isle of conquest BG your fps will still be low regardless of how powerful your system is as the game simply doesn't handle 50+ players throwing all their cooldowns at once in the same place very well. That said, you'll still be playing at closer to 40 rather than 30 fps in those very very demanding scenarios.
Going from something like a 5800x3d to a 9800x3d will in a lot of instances literally more than double your FPS in WoW.
Old_Resident8050@reddit
Tbh playing Ashran with 9800x3d + 4080 (with Smooth Motion). I mean, FPS is always high (even counting the fake frames). As high as 80-90fps minimum (Smooth motion ON).
Also Dornogal. I mean i dont think my 9900k reached that level of performance on crowded areas ever. The 9800x3d is THE WoW chip.
cbusmatty@reddit
I have a 5800X not 3D and a 4070 Ti and my gfx never even speeds up and i'm choking in raids. It feels crazy to spend so much to just play raids with reasonable fps
RagingWatersGaming@reddit
Wow is a CPU heavy game, so an X3D chip will definitely help.
I went with the 7800X3D for the price, and it’s wonderful in WoW! I run it with a 4070 Super, have zero complaints.
I play on a mix of high/ultra @ 1440p and never go below 200fps. Outside of Dornagul, which is like 120-140ish. Then for raids and epic bg, I set the slider to 5, and typically stay well above 90 the vast majority of the time. It will dip, but I believe that’s just the limit of my GPU and not the CPU, at that point.
cbusmatty@reddit
man, it feels crazy to basically buy an upgrade for like 1200 (cause i would have to get a new mobo + ram and case at a minimum) just to get decent frames on one single game, when every other game runs fine. But i also dont want to think of how much money ive put into wow over the years :D
Sephurik@reddit
I recently went from a 5900X to a 9800X3D and I'd say that jump was easily 2x performance, paired with a 3070 (still ugh). The heavy scenarios like the guy mentioned below will still be quite low, but with medium-high settings (no raytraced shadows) I went from like 20 fps on mythic sprocket last season to like 45 fps at the same most intense section.
Stuff that heavy usually doesn't last that long though. I want to get a 9070 XT for an upgrade but also to test stuff in WoW specifically.
NoFlex___Zone@reddit
Wild that this got upvoted. You actually don’t know what you’re talking about just reposting things without context
Turbulent_Map624@reddit
Tf are these comparisons always, it's like you guys don't understand sh*
Op, there is no X amount faster, it's different for every game
Do you play CPU heavy games? Go for it, otherwise if you need the money take the 7
drewts86@reddit
Eh there's not really enough context, but I can guarantee from the results on that chart it's a GPU-limited game and the CPU isn't doing any of the heavy lifting. Games that do depend more heavily on the CPU will certainly see more uplift. It would really depend on the games OP wants to play whether he would see more of a difference.
imbued94@reddit
You're suggesting settings that would lead him to playing with what, 60fps on a 240hz screen.
Op, if you're gonna play anything competitive and are willing to turn a little overclock you're gonna fly compared to the 7800x3d.
BrkoenEngilsh@reddit
If we are using this chart, wouldn't it also imply there is no reason to get a 7800x3d? You might as well save even more money getting a 9600.
Zerot7@reddit
Future wise if they go to the (rumoured) 5080s I would probably just assume the performance gap will be the roughly the same (~5% difference) as a 4090? May help them make the most informed decision about future complete build once they slot in new GPU.
GG_Igor_GG@reddit
Don't upgrade cpu rn 5700x3d is still powerfull enought to keep up with 5080S or 4090 and next year there are leaks and rumors of AM6 droping so if I would be at Your place I would wait and skip am5 and go strait to am6
T-Brie@reddit
I would consider what difference the cpu makes to total system performance vs what difference it makes on the total price. I would argue that you are getting 10% more performance for less than 10% increase in the total price of your system.
Kokoro87@reddit
Isn’t the 9800 just a tad faster in productivity?
psimwork@reddit
Honestly I wouldn't make any decisions on CPU/Platform upgrades at all until you get the new graphics card and you run some testing.
The 5700X3D is still a solid CPU, so it's quite possible that with a "Super" variant on either the 5080 or 5070 Ti, the difference wouldn't be noticeable, and you can delay the upgrade of that for an even bigger upgrade down the road for the same money.
ravanlike@reddit (OP)
oh yea, I know 5700x3d is solid. Upgraded to it from 5600 with mind that it should be enough even after GPU upgrade. But there a change of plans came. My gf's PC (or rather PSU) has died, rest of hardware is too old to justify spending any money to revive it, so either would get her some basic am4 build and reuse ssd and case, or give her what I have and get myself something new (which I was considering possible if 5700x3d cant keep up with 5070tis/5080s.
SilverKnightOfMagic@reddit
the 5700x3d can keep up.
probably best to upgrade her to 7600x/9600x build and then upgrade yourself to am6 when it comes out.
but if you didn't want to wait just buy what ever I'm your budget
ravanlike@reddit (OP)
I've heard so about asrock. I remember asus also had problems in the beginning of am5 (when first x3d chips dropped), so I will stick to msi or gigabyte
mentive@reddit
I've found ASUS tends to be the best with training memory and such... Gigabyte, not so much. Asus hasn't had any major issues since (aside from denying warranties on laptops and other reported nonsense lol)
No personal experience with MSI, but I won't go near Gigabyte again.
ravanlike@reddit (OP)
Why so, is that bad? I was thinking about getting b650 aorus elite v2
mentive@reddit
For example, I couldn't get some 6600 dominators to pass memtest86 at XMP. Had to down clock the ram to 6200. Recently switched to a cheap ASUS board, and shockingly, it succeeds with flying colors. Same professor, same ram, etc.
I had some other issues where gigabyte support was blaming my case because what I was experiencing wasn't normal. After providing more evidence, I was told it was running within spec and is fine even though I was experiencing major throttling, after he previously agreed that it wasn't normal. Refused to escalate, couldn't get anyone else, blah blah blah. Long story on that one, but the pure lack of knowledge, bs, and being unprofessional set me off.
Although ASUS is known for not taking care of warranties, their stuff just works, and I've realized I had more issues with Gigabyte products than I had realized prior.
I just personally won't ever buy Gigabyte again.
ravanlike@reddit (OP)
Thanks! Good to know. I got Asus b550 tuf and so far no problem. But that issue with blowing 7000 x3d chips and their approach made me think to avoid it. BTW, ddr5 6000 cl30 and 6400 cl32 cost the same, normally I would take faster, but I've read that am5 have problem with running anything above 6000. Is this still valid?
mentive@reddit
My understanding is, for AMD you want 6000/30
Scenario above was with a 14700k. I recently moved to a 9950x3d. I'm not exactly a hardware expert either 😁
disgruntledempanada@reddit
Running a 5090 with a 5800X3D right now. Loving it, holding out another gen before upgrading to whatever AMD brings out next.
Depends on the games you play and your workload but I've been more than happy with the 5800X3D still.
Jacobbb1214@reddit
30% price difference and 10% performance increase you literally fucking answered yourself..... in a pure mathematical sense, but again you are a human being and you might value performance increase differently, we do not know your utility function that describes trade off between increased cpu performance and disposable income, only you know what that function is......
sleeksealravioli@reddit
just a thought, it might be $130 bucks now but it could be the make or break difference in squeezing out one last AAA title in 3,5,7 years. I am in that very predicament right now where BF6 runs "okay" on my PC but now where i'd like it to be. I was in this same mindset between the i5 8700k and i9 9900k when I built my PC 6 years ago, if I had went with 990k I would of been golden, but now I might be getting a new PC.
Brevard1986@reddit
7800X3D paired with something like a 5070ti is perfectly fine and pretty optimal at this stage for 1440p gaming at 100+ FPS for pretty much every game for at least the next 2 years and then you just need to tweak settings a little to get another 2 years out of it.
Your GPU will be the bottleneck in everything except the most CPU demanding of games in the next few years.
Visible_Witness_884@reddit
No, it's most definitely not worth it.
BlazeSickn_TTV@reddit
I had the same question few weeks ago. But ingot the 9800x3D because it’s an unlocked CPU.. makes it more future proof for me
Stonesneakers@reddit
Buy 9700x, way cheaper than 7800x3D, same performances
MrPapis@reddit
7800x3d is best value no doubt.
But it also depends on the games you play. If RPG's/singleplayer then 7800x3d is more than adequate even with a GPU upgrade.
Want to maximize FPS in BF6 9800x3d isn't a bad choice it might even hold you out a second GPU upgrade.
But yeah at this point there isn't much practical difference between them, very few games are so CPU heavy.
Lordrew@reddit
Fun thing is, you can run an offset to increase the 7800x3d for about 10% cine bench preformwnce
Powerful-Ad2869@reddit
Where im from, the difference is only 40 dollars.
No_Spare1827@reddit
Id go for the 7800x3d, unless u have a 5090 wilony notice the difference. Me personally I returned my 9800x3d and got a 9950x instead but I multitask pretty hard
ZygomaticCapstone@reddit
I'd argue that with an RTX 5090 wouldn't the bottleneck always be the GPU? Since most people play in 4k if they have an RTX 5090
ZygomaticCapstone@reddit
I have 7800x3d and an RTX 4080 Super, I want a better graphics card than a better CPU, my bottleneck is always my GPU. I don't think it's worth it.
ZygomaticCapstone@reddit
Even in battlefield 6, 2042, battlefield 5, and battlefield 1
imhim_imthatguy@reddit
9800x3d runs A LOT cooler, so pick your poison.
clark1785@reddit
Even with all these numbers I think you will see a difference with 9800x3d moreso than 7800x3d. I see a lot of reviews saying they love the improvement after the fact. If a 30% price difference if you can fit it in your budget I think is worth it
Effective_Top_3515@reddit
Get the 9800x3d so you don’t come back having buyers remorse cause you bought the 7800x3d. 9000 series now have the vcache under the die so it’s much easier to cool plus it’s a newer node, more L1 cache, higher base and boost clocks.
macthediablo@reddit
I have the same question, but mostly i'm playing path of exile 2 all of the time. Which one should i get? (going from an R7 2700X)
tyrannictoe@reddit
Just get the best. If you play shooters at all, you will play at 1080p at some point. The gains can be massive in some titles.

I dont think even a serious high graphics gamer will need anything more than the 7800x3d for a good 4 more years or so
Derbolito@reddit
Upgrading from a 7800x3d to a 9800x3d doesn't make sense, but if I have to decide between the two, I would definitely go with the 9800x3d. The average performance advantage of the 9800x3d is a bit misleading, since most of the games are GPU limited, dragging down the advantage. On really CPU intensive games the 9800x3d achieves 30% more fps (15% comes from just the IPC + 30-40watt of higher TDP + 400/500mhz higher clocks).
To elaborate a bit more, I would pay attention to the concept of average when comparing CPUs for gaming, it doesn't work the same way as for GPU. For instance, if we take two GPUs with the same architecture (let's say 4060 and 4070, ignoring details like the VRAM capacity), and we say the 4070 is 30% faster than the 4060 on a set of 100 games, I would expect that in some games will be 27% more, in others 33% more. Low variation. However, a 10% advantage of the 9800x3d over a 7800x3d over 100 games more likely means that in 80 games they perform almost the same due to GPU/engine limitations, while having a 30/40% advantage on 20 cpu intensive games. High variation. Since the FPS "drawn" by the CPU are a hard limit for GPU performance, you want to maximize the performance in the worst case scenarios, also for future-proof reasons. That's why the average fps is not a good metric to look at when comparing gaming CPUs.
Narrow-Ad-9582@reddit
For CPU intensive games for sure get 9800x3d. I had the same dilemma. This is how I solved it for myself. Ask your self 2 questions:
Would $130 break my bank? If answer, yes, get 7800x3d. If answer no, go to the second question.
What else I can spend $130 to improve performance in games by 10%? I have 9070xt and next upgrade is 5080 which is over $1k. I got my 9070xt for $700. 5080 is better by 10%-15% at a cost of at least $300.
9800x3d shines in lower temps and better 0.1% lows. Average fps won’t change much.
I play heavily modded RDR2 at 4k ultra. With 7800x3d I was getting 0.1% 22fps and temps reaching 80C. Cooler sounded like turbine. Returned 7800x3d and got 9800x3d for $100 extra. 0.1% lows never drop below 30fps and temps don’t go over 65C. Cooler is dead quiet.
ravanlike@reddit (OP)
those are reasonable questions to ask.
no, it would be still in my budget (at some point of time i made side budget just for hardware and putting there something every month, should be enough for 9800x3d + 5080s if nvidia won't try to screw us)
only piece to spend more would be gpu and that 130$ could be useful to close the gap between 5070tis and 5080s (but at the end I'm able to get 5080s even if overpriced, but I refuse to be screwed by nvidia)
Narrow-Ad-9582@reddit
Again, you do not gain much average fps with 9800x3d at 4k. With 7800x3d my average were at 55fps, with 9800x3d they are at 60fps. The big improvement was in 0.1% low. RDR2 does have some very crazy physics, like horse’s testicles shrink when in cold water. That’s a CPU responsibility to calculate that you are ridding a male horse, that you enter pool of water which is below certain degree and over certain depth, now CPU send command to GPU to render testicles shrinkage. All this needs to be calculated in real time. There are too many of those small details in this game (like horse sweating over 25C). All those small calculation affect 0.1% low.
That’s my understating why such a big difference in 0.1% low in this particular game.
dervu@reddit
When people calculate $ per fps they should take into accounts also 0.1% when comparing x3d vs non x3d.
bafrad@reddit
That’s for you to decide
ChaoticReality@reddit
Just do the 9800x3D and be good until the next socket

Aiming too high get 5060 Ti 16Gb beefy for price to performance atm I got one for $449
PervertedPineapple@reddit
Maximum money saved? Stick with 5700x3d a while longer
Need new gen and save some cash? Get 9600 or 7700 (or similar) since at 1440p gains are not as massive as you think it would be.
Want to better your lows and max out? 9800X3D
7800X3D is also a good option if you can get a good price/bundle.
I game at 1440p as well as ultrawide. When I jumped from a 5600 to a 7800X3D the jump wasn't much in all the titles I play in. Biggest difference was that my lows jumped up to below my avg so the experience overall was smoother but I didn't gain 30+ fps. BG3 and SM2 did get a noticeable boost but those are CPU intensive.
Moving to a 9800X3D was another small jump but not jaw dropping.
Games like BF4 finally saturate 360Hz at 16×9 and 240Hz UW.
Recommend looking at benchmarks on titles you play.
illicITparameters@reddit
Absolutely not, and I own a 9800X3D
aragorn18@reddit
Don't think about the price difference of the individual component. Look at the price of the whole PC.
For example, if spending 5% more on the whole PC got your 10% more performance, it's absolutely worth it.
caffeine-182@reddit
That’s silly… compare the price with its alternative
OP, no the 30% difference in cost is not worth it.
aragorn18@reddit
Yes, compare it to the alternative, but keep the whole cost in mind. Compare a build with component A and the same build with component B. Build A costs $1,000 and gets 100% performance. Build B costs $1,050 and gets 110% performance. The extra 5% cost with going with build B nets you 10% more performance.
caffeine-182@reddit
Again, stupid reasoning because you aren’t comparing the rest of the build to itself
If you’re buying a new sink for your kitchen, do you evaluate and compare all the alternatives at the store, or do you divide the cost of the sink to your entire house? Obviously the you don’t because that’s stupid.
aragorn18@reddit
OP is also being required to buy a motherboard and RAM at the bare minimum and is talking about buying a new GPU soon. Those should all be included when deciding what to buy.
caffeine-182@reddit
none of that has any relevance on his cpu decision
blackholes__@reddit
literally all of those components come into consideration when buying a cpu... if i bought a 5070 or less I would not have bought the 9800x3d. If i bought a 7800x3d i might have opted to air cool instead of an aio. my pc cost $2100 and I absolutely weighed costs of the entire build against performance.
you might do it differently, and that's fine, but you're comment is very unhelpful.
AbanoMex@reddit
i think Air Cool also works well with an 9800x3d though.
ravanlike@reddit (OP)
i hope so, I was thinking about getting arctic freezer 36 in both cases.
got endorfy fortis 5 (air, single tower, double fan) on 5700x3d (105W tdp) and it works perfectly fine in this config, so i assume air cooler on 9800x3d should be fine too
blackholes__@reddit
can confirm an aio is overkill but i wanted the look lol
ravanlike@reddit (OP)
well I see his point. considering pc as a whole with performance measured in fps while gaming.
when looking only on gaming performance of pc, if extra 10% fps cost additional 100 usd, it doesn't really matter which component was upgraded and what was its previous price, at the end extra 100 usd put into pc ended up with extra 10% of pc performance
aragorn18@reddit
If you only ever looked at the price of each component, you would end up with the cheapest model for every single piece. A $60 SSD might be 15% faster than a $50 SSD, but it's not a bigger impact than the 20% price difference. So, you're stuck with the cheaper SSD.
Repeat that process for every possible component and you end up with a bottom-of-the-barrel trash PC.
isotope123@reddit
Right, but if you're reno-ing a whole kitchen, the cost of the better sink is inconsequential to the overall cost of the kitchen...
caffeine-182@reddit
By that logic, just buy top of the line everything then. Cost doesn’t matter.
isotope123@reddit
If you have the budget, yeah.
TwoCylToilet@reddit
False equivalency. I could also go all the way to the other spectrum and say that if you're building out an automotive workshop with a central compressed air system (analogous to CPU), everyone who uses pneumatic tools (software) will have down time and non-working tools if you undersized your system. So if you do not divide the cost of the system to your entire workshop, that's also obviously stupid.
Obviously the decision making is somewhere in the middle. The most objective metric would be, for that additional performance in the specific software you actually use, is that extra $xxx dollars worth it to you?
caffeine-182@reddit
The 7800x3d is not undersizing his system
TwoCylToilet@reddit
And you have missed the entire point.

True, but it would only apply if OP is actually CPU limited, which most people are certainly not. Even at 1440p for most games with those GPUs.

OP is the one who said 10% performance. It's not my job to confirm if their workload will actually see that sort of improvement.
iflyfree123@reddit
I was in the same boat, and decided to get the 9800X3D anyway. I use a 9070XT at 1440p ultrawide and still see some bottlenecking sometimes. I play a lot of Sims 4, and that game is very CPU demanding so it makes sense... but I decided to buy the 9800X3D because I was just going to sell my previous CPU anyway and so it made sense to me.
flynryan692@reddit
I went from the 5800X3D to the 9800X3D and havent looked back.
banxy85@reddit
If you would spend that price difference on another component then go with the cheaper option
If the remaining components are in budget regardless then I'd just ask yourself do you want the best, or do you want almost the best. And do you want to potentially upgrade in a few years or build a system that will last longer without upgrading

If money is a factor, 7800x3d definitely. If you'd like to save even more, the 9700X is a great non-x3d option.
FluteDawg711@reddit
I just had the same dilemma. You won’t notice the difference in performance but I went with the 9800x3D for longevity purposes. Also it will have a better chance of maxing out my 165hz refresh rate so I feel confident I’m not bottlenecking my 100’s of $$$$ worth of a GPU 🤑. Also the 9800x3d runs cooler while gaming and I’m building a SSF in a fractal terra.
Microcenter if your lucky to live by one has it for $460 right now.

I don't get why you want an x3D CPU but if you absolutely want one you should wait for 9600x3D
ravanlike@reddit (OP)
because moving from 5700x3d to 7600x, 9600x would bring negligible improvement. So if I have to move, I want this move to at least bring some positive change.

Higher tier components cost more than the performance increase they give. This has always been the case. If you want the best you're paying a much worse price to performance ratio.
For some people it's worth it to have the best. For most people it's not. And really something like a 9600X is giving you 90%\~95% of the 7800X3D performance for less than half the price, as that CPU is <$200USD in many places. So for even the 7800X3D you're paying a massive price premium.

I'm aware, that this move is not most cost efficient, especially on 6900xt, but either this or getting my gf some cheap am4 build which quite likely will be thrown away in half year (if I need to move to new platform after gpu change)

My take on what is "reasonable" depends entirely one what you're comfortable spending, and what you think is most important for your system.
Most of the people on this subreddit (and especially on u/buildapcforme) are extremely cost to performance focused for the most part to the point of making fun of people for choosing aesthetic choices over performance. At the same time I've had people argue heavily in favor of going with X870E and PCIe 5.0 SSDs because "that's what you do when you buy high end systems". I strongly disagree with both of these lines of thought.
The point of custom building a system is to build the system you the user wants. For most people they do just want the most performance they can get within some budget. But some want good enough performance with aesthetics being just as if not more important. Otherwise want specific types of hardware because they want to geek out and play with them regardless of if it "makes sense" from a performance standpoint. And some people want a specific level of performance and just don't know what hardware that requires or what it'll cost, and mostly don't want to waste money going over that.
And that's not even talking about people looking for general gaming systems, vs esports focused, vs 3d modelling, vs game dev, vs scientific work, vs LLMs, vs photo editing, vs stock trading, vs basic office work, etc. etc. etc.
This is the great thing about building a system from scratch is that you can actually pick out the components that best fit the person and their interests / means.
...
So, does a 9800X3D make sense for you? If the price difference is enough to make you question it, then obviously not, no.
A 9600X with 6400 CL32 and FCLK 1:1 in the BIOS will get you extremely close to a 7800X3D. But that may be more tinkering and risk than you're willing to deal with as you're not guaranteed to get that to work as enabling FCLK 1:1 with 6400 MT/s RAM doesn't work with all Ryzen 9000 CPUs. Where as the 7800X3D may be twice as expensive but that level of performance is guaranteed. So that cost may be worth it to you to not have to faff about with BIOS settings. Or that might be something that interests you if you like messing with overclocking.
I would certainly recommend an AM5 system today when buying new if you're looking to be able to upgrade again in the future, as AM4 is end of life. And while AMD does keep releasing new CPUs for it, they're all slower than the (now discontinued) 5700X3D. AMD is going to release at least one more generation of CPUs on AM5, and there are rumors it may be as many as 2 or 3 more generations beyond the 9000 series. So I think you're making the right decision there.

I agree with so many statements of yours, that i'm not sure where to start.
speaking about "paying extra for aesthetics is a waste" and "x850e is a must for high end", I disagree with both of them too. I will be getting fractal north because it looks good (on top of good performance), at the same time i see no point in getting anything other than b650.
that's interesting but valid approach, if I have to ask about getting something, then I dont need it. With my analysis paralysis and tendency to overthink, I think I'm more prone to having doubts. But at the end I know that neither of those cpus would be a bad choice. One might be more optimal than other, but generally both are beast cpus and as long i can afford them i'm not making mistake.
regarding ram oc and bios in general: I dont have problem with getting into bios to tweak stuff, had to remove 25mV on all cores of cpu so it wont hit Tj max during occt stress tests. With ram i never tried oc, got 4 sticks so memory controller in my current one is quite on edge anyway (it happened 2-3 times in last 2 years that it was stuck on ram test during post), was thinking about lowering speed by 133 MT but havent happened for quite a while so i left it as it is.
BaronB@reddit
Ryzen 5000 CPUs were weirdly and somewhat uniquely happy with 4 sticks of RAM compared with other DDR4 CPUs.
Do know you do not want to run 4 sticks of DDR5 with current gen consumer CPUs, always run 2. If you need to upgrade in the future, unless the next generation of AMD CPUs get a major upgrade to their memory controllers, replace the 2 in the system rather than add more.
The North is a great looking case with decent performance, though the stock Aspect 140 fans that come with the case can be a bit more noisy than normal due to an unfortunate interacting with those fans and the front slats. But if you keep the fans below 50% speed it's not an issue. Otherwise it's common for people to replace the included fans with two beQuiet Silent Wings 140 or three Noctua NF-A12x25.
TheKitler@reddit
Why change your system at all? Are you being held back by your setup in any way?
ravanlike@reddit (OP)
my gf's pc died, so I can either build her something cheap or give her what I got and get myself something new
TheKitler@reddit
Oh, that makes a lot more sense. If I was in your spot, I'd build a new 7600x/9600x system for yourself and take your GPU with you unless your gf needs something that powerful. You're already happy with the performance you're getting so why overspend when you don't have to?
Then buy your gf a GPU that's reasonable for her needs.
Ponald-Dump@reddit
Not worth it. 7800x3d
DampeIsLove@reddit
I think you answer your own question in the post title.
ccipher@reddit
Do you have 4090/5090? If not, 7800x3D.
BetweenThePosts@reddit
I got the 98 for the better thermals
natidone@reddit
Depends on what you play. Esports or sim games - 9800x3d. Everything else - 7800x3d.
Elitefuture@reddit
Depends on the games and settings you play.
If you mostly play esports games and have a good monitor, then the 9800x3d will give a bigger boost than 10%.
TalkWithYourWallet@reddit
Upgrade your GPU first, then decide
The 5700x3D is still a fast CPU, and CPU-limitations aren't a guarantee, it's situation dependent
JustForThis167@reddit
its definitely worth it. On competitive games you want to lower graphics settings which puts more burden on the CPU. You mentioned you have a 240hz display so id assume you want to play those. Cost per frame jumps off a cliff as you go up in tiers. I remember the 3090 being 2x the value in terms of cost per frame of the 3080 despite only being under 20% better at 1440p.
9okm@reddit
Get the 7800X3D.
