Hardware recommendations for building a good Linux gaming rig? (sopuli.xyz)

I know the first thing everyone will say is to use an AMD GPU. Agreed, sounds good (NVIDIA is sucky on my current machine). I have no clue which ones to start looking in to however.

I'm someone that is pretty good with the software side of computing, but not so much with the hardware side. I can comfortably construct a computer, just don't know much about what the best components to buy are. Any hardware suggestions / recommendations (for any component) are greatly appreciated (reasons for the suggestion is an optional bonus I would appreciate).

As for budget, I probably don't wanna spend much over $2.5K USD. $1K to 2K is probably about my preferred budget.

Thanks in advance to anyone that decides to help out.

(For anyone asking what I'll likely run on it: Arch Linux)

Why two sticks of RAM instead of four? Is there some kind of issue with how Linux handles it or do these CPUs not handle it well or something?

[–] thejevans@lemmy.ml 9 points 11 months ago (1 children)

4 sticks will still run in dual channel mode and it will add complexity. Depending on the motherboard and memory kit, there might a slight boost in performance, but there is more likely going to be a performance hit due to the added complexity. Since this person is building from scratch, and a two stick kit tends to cost the same as a four stick kit, it makes more sense to go with a two stick kit.

Thanks. Haven't been into the desktop scene in a while so was unsure why four sticks would be a worse idea. Always thought it would be better than two.

It's not a Linux thing or a specific CPU thing, just a general hardware thing.

It puts more stress on the memory controller, DOCP might not work which is essential for Ryzen since it likes fast RAM.

I wouldn't have thought any board newer than the original Ryzen platform X370 has a problem with this. Do they?

Besides, the fact that these two CPUs have more cache and all cores on a single CCD makes them much less dependant on fast RAM.

You could run the 5800X3D with 2800 memory and get very close to its maximum potential already, it's crazy.
