I have the MSi 7850 Twin Frozr III/OC running on 12.4
Everything seems to be working fine, I guess, but should I download and install 12.6 to keep it up to date, or just wait for 12.7 to WHQL, since it's already in beta.
This is a never-ending game. By the time 12.7 WHQL is out and you are thinking about installing it, 12.8 beta is already out and your question is raised again " Shall I install 12.7 WHQL ?".
