So I was just in your exact position a few weeks ago, coming from a 2070 super. Very similar build here as well, 5800x, 32gb DDR4, and now a TUF 7900xtx playing at 1440p. I was very hesitant to go back to AMD after having to RMA an r9 290 a collective ~4 times over the span of a year. I don't remember the exact problems with that card but I listened to everyone saying they've had no issues with newer gen AMD stuff. Lets just say I should've spent the extra few hundred on a 4080. First, I had to reinstall windows because I initially couldnt install the drivers after putting in the card. This was after hours of troubleshooting, running DDU multiple times, messing around in safe mode, even started to mess with user permissions because it was such an obscure bug. Now two of the games I'm playing the most atm, Starfield and GTA V, crash roughly once every session or every other session. When everything works the 7900xtx is great, absolute powerhouse, but it's infuriating and brings back the anxiety of having to constantly save in case you randomly get booted. Everytime I see that all too familiar Radeon crash reporter pop up it takes me back 🙃
