I haven't had any issues with my 5700XT, other than the initial drivers when the card was launched, until recently. Currently using the 20.9.1 driver which I rolled back to after issues first popped up with the newest driver, however I am still experiencing game crashes.
First Civ V started crashing - a game I have never had problems with with over 3k hours of play time. Then D3 started crashing, although much less frequently; and then Wolcen started crashing. I fixed the first issue by verifying integrity of files, but that is not the issue w/Wolcen. It could be the game and not the driver, but the game engine has long been optimized for AMD. As for Civ, the game is currently ok, but what caused the files to get corrupted in the first place? D3 crashes much less often and friends have mentioned their D3 games crashing also while using nV cards; but while typing this my Radeon software stopped working!
I have no driver features enabled other than Freesync and Freesync is also enabled on my monitor.
Other than the vid card and the RAM, my sys is about 4 years old and has been 100% stable:
