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)
