I'm building a new controller "10ft" gaming PC for my living room. The CPU is a Ryzen 5 3600X and the motherboard is Asus ROG Strix X570-I. I have never done a Linux-based gaming PC before and I want everything to "just work" as best as possible.
I assume this means go with Bazzite and an AMD gpu? Anything else I need to be aware of? As I said the goal after configuring is for it to be entirely controller-controlled (8bitdo ultimate and DS4).
If you're doing 1080p the 6600 is pretty solid. Or 7600, really. It CAN do higher resolutions, but then you'd need to start doing FSR scaling or drop settings to keep things smooth/consistent.
It seems to me that 6700xt is much stronger than 6600. More expensive, too. Personally, I would pay some extra money 6700xt, but it depends on OP's budget and game preference.
I'd suggest OP to consider several factors:
Is the game you're playing CPU-intensive? aka Will your 3600X be the bottleneck if you have a powerful GPU?
HardwareUnboxed did a with/without ray tracing comparison. TL;DR in most games it's not worth the performance hit. Don't bother with ray tracing for now, especially on low or mid-range hardware.

AMD with ray tracing isn't great. Not as bad as it used to be, but pretty lackluster overall compared to Nvidia (and to a lesser extent Intel's GPU offerings). Linux ray tracing via Proton is also not as optimized at present, so that can take something "passable" in windows and make it unplayable on an AMD card in Linux. If you get something overkill for the resolution you're playing at that can somewhat make up the difference.
