10 years since last build (1700X + 1080Ti), sanity check on new gaming + CAD build (Intel vs X3D?)
Posted by InvestigatorRich9521@reddit | buildapc | View on Reddit | 30 comments
Hi all,
It’s been about 10 years since my last build (Ryzen 7 1700X + GTX 1080ti in an In Win 303) I already sold it 2 years ago and currently using a laptop 2021 Asus zephyrus G15(5900hs, RTX 3060) and i cant stand it anymore LOL, have just recently watched a few reviews so I’m a bit out of the loop and would appreciate a sanity check on my planned upgrade.
Use case:
Gaming: AAA titles + some emulation
CAD (hobby, possibly business later): AutoCAD, Fusion 360, Inventor, Revit MEP
Possibly AI workloads? not sure yet as to what can i do so this does not really matter for now but open to suggestions (i'm a mechanical engineer).
Monitor: Acer Predator ultrawide (3440×1440, 100Hz) really old but still works great
I understand CAD tends to favour strong single core performance, while for gaming X3D CPUs is King. I’m currently leaning Intel for a more balanced setup, but open to being convinced otherwise. Also, if I build with 9950X3D which I really like to but cant justify spending an extra $AUD700 for little performance gains. I want this build to last 5 and possibly stretch to 10years (tech progress is crazy so this build might not even last that long compared to future PC performance but we'll see).
TIA
| Component | Selection | Comment |
|---|---|---|
| CPU | Intel Core Ultra 7 270K Plus 3.7 GHz 24-Core Processor | Chose this CPU as it seems like its a good balance for both gaming (3440x1440) and productivity/cad work at this price point. |
| CPU Cooler | Deepcool ASSASSIN IV 79.1 CFM CPU Cooler | I like the looks, also has good reviews (dont want to spend too much as i might go full custom loop in the future if i get bored) |
| Motherboard | Gigabyte Z890M AORUS ELITE WIFI7 ICE Micro ATX LGA1851 Motherboard | cheapest Z890 i could find in Australia |
| Memory | G.Skill Trident Z5 RGB 48 GB (2 x 24 GB) DDR5-8000 CL38 Memory | i've read that intel scales well with high speed memory so i chose this 48gb which i think is more than enough for the 3D models i will be working on and because higher capacity with high speeds is freakin expensive |
| Video Card | Gigabyte AORUS MASTER GeForce RTX 5080 16 GB Video Card | chose this card as i like the aesthetics but still on the fence, because if i go custom loop might as well go with a cheaper card as shroud looks wont matter. |
| Case | Lian Li A3 or Deepcool CH270 | still on the fence between these two, I like the vertical orienation to save space on the desk (1500x700mm) and will still have a nice view of the insides. i also might go full custom loop in the future. for the A3 i'll be 3D printing a base to change orientation to vertical. |
| Power Supply | Cooler Master V SFX Gold ATX 3.1 850 W 80+ Gold Certified orDeepCool PS850G 850W Golden Dominator SFX (this ones cheaper) | i dont really mind what PSU to get as long as its sufficient for the 270k plus and 5080 and SFX 850w gold as minimum so it can sit nicely in the case. |

I would not spend 450 extra on the same GPU. I do think for your usecase the 270K plus is fine, even though you are limiting yourself in the future. An AM5 CPU would allow you to upgrade either CPU or GPU, as the CPU is a lot more powerful in gaming, in the future.
InvestigatorRich9521@reddit (OP)
Thanks, i do agree. Also, i can get a cheaper B850 motherboard vs the Z890 which will be a dead end platform. The only reason for the Aorus master GPU is i want a nice looking shroud :D. but I guess it will be covered by a mesh anyway and only visible from the side? it will be around $200 to $300 more for more depends on the MB i get for future flexibility.

Going AM5 for upgradability really isn't worth it. It'll only get one (confirmed) or two (rumoured) more generations and then they'll go to AM6. So there isn't much to upgrade to anyway. And the 270K Plus simply offers a lot more performance for the same price.
Lonely_Platform7702@reddit
I disagree with this as someone who is still on a B450. I started with a 2600X / 1070Ti, then a 3700X / 3070 to now a 5800X3D / 5070Ti. I am very happy i can still use AM4 after 10 years.
The 9900X3D outperforms the 270K plus in gaming. Which OP will mainly be doing besides some hobby work. You don't know how big of a jump the next generation of CPU's will be. The 270K plus will limit anything higher than a 5080 in a lot of games at resolutions up till 1440P. Why limit yourself? You don't know what the future will bring.
YourMajesty90@reddit
Always found this a terrible argument. OP wants this build for the long run. By the time he needs to upgrade his CPU again he will most definitely need another mobo as well. So that point is moot.

Looks solid, a few ideas for tweaks:
InvestigatorRich9521@reddit (OP)
Thanks for the suggestions.
killzone44@reddit
I had to get a new case vs my 15 year old case I'd been building in multiple cycles. Wanted support for at least 1 420mm radiator, and more HDD's than most cases support these days. Ended up with Thermaltake CTE C700. It's a weird layout, and I did end up needing to buy some longer cables... but it works for my HDD storage, huge radiator, and fits long GPU's easy.

For cooling I'd actually recommend just getting an air cooler. It's by far the most reliable option.

The first point is literally what I said earlier, and you dismissed it.
MS are not noticeable unless you’re running months-long workloads, for which performance gains add up to hours-days.
InvestigatorRich9521@reddit (OP)
I did not dismiss it though? I upvoted your comment as it was a good point and thought didn’t require a detailed response.

The higher the speed of your memory the smaller the gains. I would get a larger capacity kit with slower timings that are still decent (like 6000 or 6400) rather than less capacity and higher speeds.
InvestigatorRich9521@reddit (OP)
Thanks, This is what i found without increasing the total cost much. Is this ram good 64gb 6600 cl32, Its in the qvl list as well.

Annual-Fan-4944@reddit
Yeah that's alright. It's incredible seeing 64GB over 1k USD now...
InvestigatorRich9521@reddit (OP)
yup, crazy times. everyones price gouging everyone.
found this one too 96gb 6000mhz cl36. for $50 more.

As an AMD owner I agree Intel much better suited to this use case
InvestigatorRich9521@reddit (OP)
Yeah i’m torn between 9950x3d as it’ll only cost around $AUD300 more if i get a cheaper RTX 5080 as the motherboard will also be cheaper if i go with a B850 my only worry is the AMDs sensitivity with RAM which is hard to find good ones without paying with an arm and a leg.

64GB DDR5 at standard 6000Mhz xmp profile is better. Especially for gaming.
YetanotherGrimpak@reddit
That's for amd, this is intel.
prank_mark@reddit
Yeah but even then you'll benefit a lot more from 64 vs 48 GB than from 8000 vs 6000 MT/s. Especially when running AI models. I'd definitely go 64 6000 over 48 8000.
InvestigatorRich9521@reddit (OP)
Thanks, yeah 64gb is more beneficial in the long run specially with programs using more ram, i also just checked some benchmarks and you are right the performance gain from 6000 to 8000 is negligible for my use case, and only beneficially if i am chasing highest benchmark scores or really need that extra 1-3%.
YetanotherGrimpak@reddit
On that I can't disagree.
j9519KC@reddit
Maybe a 1000w power to be safe but i don't have a 5080 so idk
InvestigatorRich9521@reddit (OP)
Yeah might upgrade to 1000w as someone suggested a 3090 or 4090 for LocalLLM which caught my interest.
Character-Mango6061@reddit
fwiw i’ve been running an 850W gold psu with my 13600K + 3090 for years with no issues
InvestigatorRich9521@reddit (OP)
Thanks for confirming, just checked 850w is well over the full load of the 5080 and 270k around 750w . I don’t think i will be running the pc 100% load at all times but having more isn’t bad though will just cost more.
RumbleTheCassette@reddit
Looks reasonable to me.
I'd also say, if you're considering using the system for business needs, I'd avoid the custom loop. They can be very reliable but also, when something goes wrong, it's gonna take a lot more down time to address than if you just use an AIO or fan cooler.
InvestigatorRich9521@reddit (OP)
Good point, sticking to an air cooler then. Thanks!
bombastic6339locks@reddit
Looks fine
