Posted by Dismal-Chip-939@reddit | buildapc | View on Reddit | 35 comments
Hey everyone! Planning this enthusiast build for 1440p 360Hz gaming and professional streaming. I’m looking for the best balance between performance, noise levels, and aesthetics. Any thoughts or potential bottlenecks?
- CPU: AMD Ryzen 9 9950X3D
- GPU: ASUS TUF Gaming GeForce RTX 5080 OC
- Motherboard: MSI MAG X870 Tomahawk WiFi (USB4/PCIe 5.0 support)
- RAM: 32GB (2x16GB) G.Skill Trident Z5 Neo RGB DDR5-6000 CL30
- Main SSD: Samsung 990 Pro 2TB Gen4 NVMe
- Extra Storage: Mixed SSDs/HDD (Reused from old build)
- AIO: Arctic Liquid Freezer III 360 A-RGB
- PSU: be quiet! Pure Power 12 M 1000W (ATX 3.1)
- Case: be quiet! Light Base 600 LX Black
- Fans: 3x be quiet! Light Wings 120mm (Bottom intake)
- Monitor: ASUS ROG Strix OLED 27" 1440p 360Hz
Would you change or swap any of these parts? If so, why? I'm looking for feedback on better value alternatives or potential compatibility issues I might have missed.
Thank you!

9950x3D is a solid choice if you are VTubing, you want the extra cores for all the background processes. RAM and VRAM are your bottlenecks - unless you are playing some light/cpu have FPS etc you will not it 360Hz 1440p. Running Horizon Zero Dawn (remaster) in high is maxing my GPU and RAM in high settings at 100FPS. If you want this level of performance I really think a two PC stream setup is for you. Or (UK prices) that GPU is £500 is from a 5090, throw in 48/64GB of RAM save some money on your monitor (and got streaming I really recommend at least two monitors so you can read chat, check OBS etc) and motherboard. Even going to something like CL36 RAM the increase in capacity will improve performance more than you lose from the increased latency. And drop to a cheaper main SSD.
Or go for a cheaper 5080 sticking with 32GB of RAM and with the other cost savings above build yourself a second stream PC.

I would get 2x24GiB (48GiB) 6400c32 and an extra 4TiB SSD for games, at it will fill-up fast
Dismal-Chip-939@reddit (OP)
I'll definitely look for a 6000MHz CL30 version of those, as I’ve heard AM5 can be a bit finicky with anything above 6000MHz. Regarding the storage, since I’m reusing about 1.75TB, I have 500GB SSD, 250GB SSD, 1TB HDD, from my old build, adding the new 2TB drive puts me at nearly 4TB total, which should be enough to start with, what do you think? Thanks for the solid advice!
ssuper2k@reddit
In my case 6400/2133 was the sweet spot

Oh you got MONEY money. If you’re looking for value swaps:
Swap the 9950X3D for a 9800X3D. 9950X3D is for heavy productivity workloads while still keeping the 3D V-Cache for gaming. If you’re just gaming/streaming, the 9800X3D will be enough and be way cheaper.
You can technically get 6000 CL36-38 RAM if it will save you $100. Since you are getting an X3D CPU, you’ll hardly tell the difference between the two.
The 990 Pro is for productivity and elite read and write speeds that come with like video editing and other stuff. If you absolutely don’t need it, don’t waste the obscene amount of money it costs to get it. Just get a drive that has TLC Nand like the 2TB Patriot P400 Lite and save yourself $150-$200.
Dismal-Chip-939@reddit (OP)
Thanks for the suggestions! Those are some really interesting points to consider.
Regarding the CPU, I've been leaning towards the 9950X3D because I plan on doing some heavy streaming with a lot of background apps while gaming, like OBS Studio, NVIDIA Broadcast, Audio Routing, Browser (Twitch Dashboard, Chat, etc.), Stream Deck Software, Discord and several peripheral management apps.
Do you think the 9800X3D can handle all that multitasking without any frame drops/micro-stutters, or are the extra cores a safer bet for a 'no-compromise' stream?
About the SSD, that's a fair point on the 'Samsung tax'. I’m definitely not set on the 990 Pro. Would something like a WD Black SN850X or a Crucial T500 better middle ground? I'm a bit wary of going DRAMless for my main drive, but I'm open to suggestions for reliable alternatives that won't break the bank.
For the RAM, I was aiming for CL30 to help with those 1% lows, but if you guys think the real-world difference is negligible with the X3D cache, I might reconsider to save some budget.
Since I haven't bought anything yet, I'm still fine-tuning everything. What do you guys think? I'm open to any swaps that make sense for a top-tier Gaming/Streaming balance!"

Do not go for the 9800x 3d. Did the same mistake, "upgraded" from my 12900k, multitasking took a very obvious nosedive. Im also at the smae boat as you, running multiple things while gaming (discords and the likes - sometimes queue up in a game and play something else while waiting for the queue to be done etc.), the 9800x 3d is disgustingly bad due to 8 cores. Go for the 9950x 3d or even the plain 9950x // alternatively 270k which is a beast especially for the price.
Dismal-Chip-939@reddit (OP)
That's exactly what I was afraid of. It's interesting to hear from someone who actually switched back because of the multitasking 'nosedive'. Usually, benchmarks only show average FPS in a vacuum, but real-world usage with Discord, queues, and background apps is a different story. Thanks for sharing that!

Are you using AI to type your replies?
BooksandBiceps@reddit
Glad someone else noticed, though I was going vrazy
Dismal-Chip-939@reddit (OP)
English is not my main language, im sorry bro. Im new at this, Im using google translate and AI to help me ask right questions, its my first PC build in 10 years, I need help, and ofc I need to check if im doing the best choices! Dont hate, much love! I know how to speak english but sometimes I make some errors typing.
vjhc@reddit
English is not my first language either, and you're not only using AI to translate, it seems you're just copying comments from users and feeding it to Gemini or whatever and using what it says verbatim for your own replies. I know I'd prefer a maybe not so good English reply to the AI slopfest I'm reading from you right now. Remember that AI will agree with you whenever it can, and confidently say the wrong thing if not told otherwise.
Dismal-Chip-939@reddit (OP)
Fair point, and you're right, I am using AI to help me phrase my thoughts and translate them into English. Since it's my first big build in 10 years and I really want to get it right, I'm using it as a tool to organize the massive amount of info and feedback I'm getting.
However, every question, doubt, and choice comes from me. I’m the one pushing the buttons and trying to understand the 'why' behind every component. I just want to make sure I don't miss any technical details due to the language barrier.
I appreciate the honesty, and I'll try to keep it more 'raw' from now on. I'm just a guy trying to build his dream PC and making sure I'm not wasting money. Much love!

Even simple things like having steam or epic store downloading in the background have an obvious hit on framerates in heavier games. I was very constantly seeing the CPU running at 90% usage just running a heavy game.
For example, this is just the game running, look at the CPU usage at the left, it's completely tapped out

Urdnot_Flexx@reddit
This is just false. It’s been disproven a long time ago: https://youtu.be/Nd9-OtzzFxs?si=THFhvYqTTrn1aEMJ
I have a 9800X3D system and YT+discord+game+browse all the time and I never lose FPS. Please stop spreading misinformation.
Good_Season_1723@reddit
LOL, guy tests single core oriented games and there was still a noticeable hit in performance. Now go try doing that in this game - look at the CPU usage, it's already at 90%

Urdnot_Flexx@reddit
If you have the money, the 9950X3D would be the safer bet when running all those at the same time. IIRC, there’s a way to allocate specific tasks to the non X3D cores with the 9950X3D, so you can learn to do that just to be safe if you’re running all that. For the SSD, the WD black would definitely be a better middle ground if you insist on DRAM. 990 is just ludicrous. Statement still stands on the RAM though.
Dismal-Chip-939@reddit (OP)
Glad we agree on the 'safer bet' for the CPU and the WD Black as a better value play for the SSD. I’ll definitely look into the core allocation (Process Lasso or similar) to make sure the game stays on the 3D V-Cache CCD. Regarding the RAM, I'll keep hunting for a good deal on CL30, but I'll keep your point about the X3D cache in mind if the prices stay this crazy.
Rusko_2@reddit
Better save this 250-300$ and bump it into 64gb ram.. You will gain more multitasking space, and if you somehow wants 9950x3d aka ryzen 9, just wait for next gen zen 6..
Dismal-Chip-939@reddit (OP)
I totally see the logic in 64GB for multitasking, but with the current DDR5 price spike in 2026, it’s a tough pill to swallow. I’m thinking of starting with a fast 32GB CL30 kit and upgrading later if needed, but prioritizing the 16-core CPU now since it's the heart of the system. Do you think 32GB is already becoming a bottleneck for gaming + streaming?
nguyenlucky@reddit
9950x3d can use the 3D CCD for gaming and non 3D one for streaming tasks.
aragorn18@reddit
The GPU handles the vast majority of the streaming tasks. You certainly don't need a 16 core CPU for that.
Dismal-Chip-939@reddit (OP)
I totally agree that NVENC is a beast for encoding. My main concern is more about the 'clutter' of background tasks that aren't GPU-bound, like real-time VSTs, AI voice processing, and complex OBS scene management.
Do you think an 8-core CPU can handle all that 'noise' without any hitching during high-refresh-rate gaming, or would the extra threads provide a more consistent experience?
aragorn18@reddit
Are you already making money at streaming or is this a hobby you're hoping to turn into a profession?
Urdnot_Flexx@reddit
GPU does the heavy lifting for streaming. 16 cores is overkill for that specific use case. You’d essentially be giving money away for no reason.
Tlentic@reddit
Your borderline 5090 territory and that might be worth grabbing if you can find a decently priced one
CPU: it’ll work fine but 9850X3D does technically perform better in most games and it’s cheaper. It’ll work fine for streaming too. 9950X3D2 is also a thing. Probably not worth the price but check some reviews and see if any of the editing programs you use would benefit from it
GPU: if you don’t go the 5090 route grab the PNY ARGB EPIC-X RGB OC 5080 for $1329.99. It’s cheaper and performs better.
Motherboard: you’re wasting money here. Only high end GPU on the market that can technically benefit from a PCIE gen 5 x16 slot is a 5090 and even that is only a 1-3% hit. This one has a gen 5 M.2 slot too for the M.2 ima recommend. Take the $100 and spend it elsewhere
RAM: grab the silicone power xpower zenith gaming 32gb (16gb x 2) 6000 Mhz CL30 kit instead for $380 in black or $370 in white. Exactly the same specs/performance so no need to speed any extra here for zero performance boost
Storage: Samsung 9100 PRO 2TB is like $80 cheaper and it’s better. Makes no sense grabbing the 990 pro
AIO: grab their new liquid freezer pro 360 instead and skip the RGB. You’ll probably end up swapping the fans out for be quite or noctia ones anyways, save yourself the needless hassle and some money.
PSU: Montech Century II 1050 watt is cheaper and the same quality
Case: they’re subject, pick what you like but just remember it’s a box. A $53 Phanteks XT Pro is more than sufficient
Fans: yeah do some be quiets or some noctua fans. Just pick something and stick with it for all of them. Skip RGB is longevity and noise levels are your priority.
Monitor: a 360hz 1440p monitor is fucking stupid unless you only play e-sport games like counter strike. You’re never going to hit 360 FPS at 1440p in most games, so makes it kinda pointless. I’d just grab a nicer ultrawide QD-OLED monitor like an Alienware AW3425DW (monitors are the only thing Alienware does well) or take some savings and throw it at a tandem WOLED monitor like a LG Ultragear OLED 27XGX790B-B. The tandem monitor will give you fantastic light and darkness + it’s 540hz.
Dismal-Chip-939@reddit (OP)
Wow, thanks for such a detailed breakdown, u/Tlentic I really appreciate the time you took to find these alternatives. You’ve given me a lot to think about, especially regarding the 'value' side of things.
I'm definitely open to dropping some of the RGB/Aesthetic 'tax' if it means better performance or significant savings. For example, I’m strongly considering your advice on the SSD and PSU.
About GPU, that PNY EPIC-X suggestion is very interesting, especially with that price difference. However, noise levels, temperatures, and build quality are huge priorities for me since the PC will be right next to my streaming mic. Does the PNY actually hold up against the ASUS TUF in those specific areas? If it stays cool and quiet while saving me some money, I'd definitely be interested.
On the Motherboard, I was eyeing the X870 mainly for the native USB4 and the high-bandwidth connectivity for my streaming gear (Stream Deck, cams, etc.), but I’ll re-evaluate if a high-end X670 could do the job for less.
Regarding the Monitor, I’ve been using a standard 24-inch monitor for years, so I’m looking to step up to 27-inch — it feels like the perfect sweet spot for 1440p without being too overwhelming. I’m not really into curved or much larger screens because they’d feel huge on my desk, and the viewing angles would be weird for friends or anyone sitting next to me watching.
I'll take a serious look at the Liquid Freezer Pro as well. If I can save a few bucks by going for a cleaner, non-RGB look without sacrificing noise levels, I might just do that.
Do you have any other advice or anything else you'd change in this setup?
Thanks again for the reality check!
IrrelevantTale@reddit
Good choice on thr 9950x3d. The 9800x3d is more than enough for gaming but if your streaming you want the extra horse power of the 9950x3d.
I have the same exact build and it performs really well, and theres a few games i play that the 9950x3d actual gives more performance. Since you plan on stream, especially if its a Vtuber kinda thing you'll want the extra junk in the trunk. I just wish the 5080 had more VRAM for future proofing.
Urdnot_Flexx@reddit
The GPU is doing most of the work for streaming. And if you’re going to make that argument, then it makes more sense to pick up the 9850X3D, which has more gaming performance than both the 9950X3D and the 9800X3D, and is still cheaper than the former.
Dismal-Chip-939@reddit (OP)
The 9850X3D is definitely a beast for pure gaming, but my main hesitation is the 8-core limit.
Since I’ll be running a heavy background load (Game, OBS, AI Broadcast, VSTs, 10+ tabs), I’m worried about those 8 cores getting crowded. On the 9950X3D, I can essentially isolate the game to the 3D CCD and let the other 8 cores handle the rest of the 'clutter'.
Do you think the higher clocks on the 9850X3D actually outweigh the multitasking benefits of the 16-core part for this specific use case?
chsn2000@reddit
Most of the streaming and video encoding is done on the GPU these days. If its within budget, the 9950X3D is a good choice because the higher core count will make a huge difference when if you're ever editing VODs or reencoding them etc.
Main thing I would throw caution to is the AIO. Arctic's mounting doesn't play particularly nice with AM5 so it's hard to justify the price premium.
The motherboard also is pretty overkill unless specifically you're going to be doing memory OC, or have already maxed out the IO.
If the savings are enough to get a second monitor and/or a decent mount, that will do a lot more in terms of usability than getting parts with ever so slightly more bling.
Dismal-Chip-939@reddit (OP)
It’s awesome to hear from someone running this exact setup! You hit the nail on the head—I’m looking for that 'extra junk in the trunk' to make sure the stream stays butter-smooth even when things get chaotic.
Have you noticed any specific games where the 9950X3D's extra cores really made a difference in stability? And yeah, I'm with you on the 5080 VRAM... it's a bit of a letdown for 2026, but I guess we're stuck with it for now!
IrrelevantTale@reddit
Star Citizen and Minecraft come. I can do 96 chunk render distance in bugrock on the 9950x3d at 80% utilization. Theres not a long of games that can use the extra cores but the ones that do the 9950x3d eats for breakfast.
