My main rig is an AMD Ryzen 7950X with a Radeon 7900 XT. I knew I wanted a 7950X after seeing it fly through Windows 9x on 86box (cycle-accurate 80s/90s PC emulator), and throw some punches playing Microsoft Flight Simulator 2020 (also why I got the 7900 XT, it's only slightly worse than a 4080). This was the rig I recently bought from a vendor and so far I'm in love with it. It does Linux near-perfectly, the liquid cooling and RGB needs a bit of tweaking but Liquidctl + OpenRGB does the trick right now.
Then, I have a gaming laptop with a Core i7 and RTX 2070 Super smushed into it. This was like a grand cheaper than buying a whole new rig, especially since the rig at the time wasn't really broken or problematic. I was also depressed from COVID lockdowns so probably wasn't my best decision, lol. This laptop served me well gaming-wise but I can't use Linux on it, like at all. Fractional scaling issues and Intel's RST makes it a pain.
Then there's my Steam Deck, which basically rendered the laptop and my Nintendo Switch obsolete. If I know I'm going to need a portable gaming system, I just bring my Steam Deck out now.
