It's my first time building a computer. I also haven't really done much PC gaming in the past 15 years, except on my Steam Deck. Actually, it is the Steam Deck that has convinced me to invest in a desktop PC with some more power. I like the Linux experience on Steam Deck and would like to stick with that if possible. I haven't used Windows in 15 years either, as I tend to use Mac OS and a bit of Linux for personal and work. Windows seems to just get worse and worse and I'd like to avoid it if possible.

In any case, I went with an AMD CPU because I've heard about Intel's recent corrosion issues. And, chose an NVidia GPU since I'd like to take advantage of ray tracing. I've heard the driver support can be a bit mixed on Linux, but I'm open to trying to make it work unless folks think it really is terrible. Any feedback is helpful.
Anecdotally run a 7800x3d and 7800 XT with almost no problems playing games using steam with proton. Had some trouble with Magicka and setting up Forged Alliance Forever was tedious. Send it.
