I'm thinking of building a pc to play a few demanding games (e.g. PEAK, Satisfactory, Stellaris) at 1080p@60. It'd be under Proton/DXVK on Linux.
GPU prices in Australia are kinda fucked atm so that would probably have to be a used card, but would anyone have any advice on what I have so far?
If you're happy hunting down a used 5800X3D or 5700X3D when you do want to upgrade, I'd say that makes sense to a degree. Just that they're both end of life so finding one might be tricky when the time comes.
I'd almost suggest going straight for one of those CPUs now even if that will require more time to save up then just upgrade your GPU in a few years. That'll make a much bigger difference even in games that benefit most from the v cache
