I read a few posts from a few years ago that they suffered from some sort of ring crash bug frequently.

If you're currently on either of those cards, how is the stability nowadays? Any hiccups or problems, or is it 100% in gaming now?

Bonus question, does the Mesa driver allow you to access the VCN video encoder on the gpu?

EDIT: Thanks for all your responses, everyone! The consensus clearly shows they're pretty balin', and definitely worthy of switching away from Nvidia to. :D
