Few months ago I built a gaming PC and chose to not use Windows for multiple reasons. I would suggest sticking to AMD as it would better supported on Linux. For the OS I’m using Arch Linux which is base for a lot of gaming Linux distributions. 99% I have never felt like I was missing out by not using Windows. Wine/Proton works really well OOTB. I highly recommend it if you want to get into Linux gaming. Like others have mentioned, ProtonDB is also a great resource for finding game specific information.
