Yeah, getting an AMD GPU has felt exactly as I predicted. GPU was cheaper, great price performance, but since it's not even close to nvidia market share, so devs just don't care to put in work to fix AMD related bugs in their games. And some issues are AMD's fault too.
For example: CS2 launched after more than a year of various levels of beta access, and even after launch AMD GPUs still suffer from insane 1-2 second freezes EVERY SINGLE TIME you load into a map due to shader compilation.
Current workaround is starting the game, and loading into every single map before joining a competitive game. Freaking cringe.
Second workaround is kneecapping all your other DX11 games by disabling DXNAVI by doing some sketchy registry hacks. Freaking yikes.
I'm not regretting getting the 7800xt, yet. But I'm on my way there.
Edit: for those wondering yes, i did just try it on the driver that just came out that had CS2 support.
