Linux PC build (2025)
Hello,
it’s me again. Some of you might remember me from this post, in which I was asking for feedback to build a Linux PC in 2025.
Stuff happened and I didn’t went through with it. So this still my first attempt at a build. Well now I’ve got time and want to try it again.
As you may notice, I’ve ditched the Z790-9 mother board in favor of a MSI PRO B650M-P. My dream of building a coreboot-system is officially dead, thus I decided to build an AMD-System.
Short Listing:
- CPU: AMD Ryzen 7 7700X 4.5 GHz 8-Core
- CPU-Cooler: Thermalright Assassin X 120 Refined SE 66.17 CFM CPU Cooler
- Mother board: MSI PRO B650M-P Micro ATX AM5 Motherboard
- Memory: Patriot Viper Venom 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory
- Storage: Acer Predator GM7000 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
- GPU: Sapphire 21323-01-20G Radeon RX 7900 XT 20 GB Video Card
- Case: Zalman P10 MicroATX Mini Tower Case

- Monitor: KOORUI 24E3 24.0" 1920 x 1080 165 Hz Monitor
If you notice anything wrong or have suggestions/improvements don’t hesitate to point them out.
Thanks in advance!!!

Everyone else already mentioned the monitor so I’ll do something else.
With newer motherboards, some WiFi/bluetooth chipsets have poor support. I had trouble with the Realtek chipset that came in my brand new motherboard. The solution for me was to buy a pcie WiFi/bluetooth combo card for about $30. Throwing it out there in case you run into the same problem.
You can definitely support more pixels than 1080p, even at 165hz. My kid has a 6700 xt and I’m constantly impressed with it at 2k 165. Worst case you can run at 1080 and upscale.
You are right the build could probably handle more, but I don’t need anything fancy. Anything beats the setup I have now. The monitor is basically just included because I need something with a higher refresh rate, than my current monitor allows.
For what you’re spending on this, I would highly recommend throwing in a 1440p monitor. The difference from 1080p is night and day. The 7900XT will have zero issues with it, and you can find a solid 27" one for cheap nowadays so long as you’re not trying to find an OLED or something with a stupid high refresh rate.
That’s about the only feedback I have here though, the rest of this build looks good!
Hardware is very similar to my own build from last fall, except I went with a 7800XT. it’s been running CachyOS since then and works superbly.
Anecdotal, but I have owned a total of 3 sapphire amd cards in my lifetime, and all 3 failed much sooner than a GPU should.
It has been about a decade since my last one, so maybe they have stopped using low quality parts, but just wanted to give that input.
I had a Sapphire RX580 fail on me in 2023. It was a cheap card I got from ebay, so who knows what the previous owner did to it though.
Why did you decide to change the motherboard? Is it because of Intel’s issues with their chips? Wouldn’t that problem be fixed with their microcode patch if you buy now?
Personally, I don’t trust 13th/14th gen chips period. I’m sure I’m overreacting but I’ve simply seen too many dead computers due to Intel’s CPU bugs in last 12 months that no amount of microcode updates will make me feel comfortable selecting one of those processors, especially when it’s my own money on the line
Well I guess if you have a GPU then Ryzen Zen 3 processors are better bang for the buck
I’m not OP, just a rando chiming in
Haha I know
I am curious why coreboot is important?
Because it lets us disable Intel ME
@marauding_gibberish142 I personally find the Intel ME a useful feature, it’s nice for example to be able to upgrade BIOS without a CPU and/or memory, this has allowed me for example to upgrade the BIOS to a version needed for a newer CPU on a board with a BIOS that didn’t initially support it without needing the older CPU to perform the upgrade. And from a security standpoint, if you do not enable and configure the network stack, and you don’t have a DHCP server available to it for it do so on it’s own, I really don’t see what it can do that is harmful.
How do you not configure the network stack? If you have an Intel NIC on the motherboard/any PCIE lanes in theory it should be able to connect.
What worries me is that someone could perform a reverse shell on my system with/in addition to a magic packet and get full ring 0 access to my system. I’m investigating network monitoring tools that can help me find traces of ME on my network.
Because coreboot is the only way for us to be in full control of the hardware. Any other way there is microcode which is closed source and we have no idea what it is doing. It has full control to everything.
There’s still microcode and other firmware blobs. Coreboot is just BIOS.
@jeena I grant you that is true, but under Linux, the kernel talks to the hardware directly after boot, not through BIOS calls. About the only time you would talk to the BIOS after boot is for sleep/suspend, or in rare cases such as the server my friendica instance runs on, for temp/CPU speed control because Linux kernel has issues properly using the MSR on the i9-10980xe, oddly it does not seem to have the same issue on the i9-10900x which is a ten core CPU in the same family, so I am forced to depend upon ACPI since talking to the hardware directly in this specific case is problematic. If you were running Windows or if you had weird hardware that is somewhat broken under Linux like mine, I can see the need, or if a laptop and you wanted sleep/suspend functionality. But for what you describe it isn’t clear the benefits. And there are some risks like it probably isn’t going to do the extensive memory training of a more advanced UEFI bios like American Megatrends, so your memory access may not be as efficient as it could be, and you’re more limited in hardware selection.
What do you plan to do on that graphics card? Is that 20GB VRAM? That sounds nice, but not being a NVIDIA it lacks at least the CUDA cores which are necessary for many AI use cases which I have.
I think Ollama supported ROCM especially with the older AMD cards?
I have ollama running locally on my RX9070, I have to use kernel 6.14 since it’s such a new GPU.
The 16G VRAM means I can run decent models, faster than I can read… currently running gemma3:12b, it’s crazy fast.
How quantized? I don’t think 16GB of RAM is enough to run a full fat 12B model at FP16 but maybe I’m wrong.
Nvidia cards are just too expensive
q4_k_m
8.1GB file size
That’s great to know. Do you regret not having the performance of Nvidia? I would prefer not to buy green but I’m not sure from the comments about the delta in performance from ROCM vs CUDA
I don’t know, it is running much faster than I can read.
So I’m not sure why more performance would be needed, the only thing I was looking for was big VRAM, and AMD gives much more bang for you buck (especially in NZ). To get 16GB of VRAM on an NV card in NZ would have set me back an extra $800…not something I was willing to do.
Have you tried bigger models?
Why the 7900XT and not a 9070 or 9070XT? Stock issue? Both are overkill for 1080p gaming but if you’re trying to future proof, wouldn’t the newer card with FSR4 be the better option?
I couldn’t find a 9070XT at around MSRP anywhere, I wanted to use them in a combination with other GPUs for AI. Know where I can find some?
AI is a different beast altogether, maybe I missed that use case in this or your previous post. From what I’ve read, rocm support for the 9070 cards is still being worked on.
Edit: Just learned to stay away from the keyboard until after coffee. Also, GPU pricing is horrible all around.
I’m not the OP, and yeah I saw that too. Thanks
That monitor will hold it back. 1080p wouldn’t be bad if modern games run without TAA blur, but most games require it. Even a cheap 144hz IPS 1440p will give you a better experience.
