So I recently got an HD7870 to upgrade from my 7770. I gave my brother the 7770. I also got Windows 8 and installed it, and it seems fine. But sometimes while I'm playing games, the computer screen will suddenly have a "checkerboard" of a certain shade of color - last time it was orange, it's been green, etc. It only happens occasionally. I've tried reseating the card to make sure it's in right, I've tried making sure my drivers are up to date (13.1), etc. I would think that it might be the card itself, but here's the thing: that 7770 that I gave my brother, the one that gave me absolutely no issues whatsoever? It's doing the same thing, so I don't really think that it's the card that is messed up. I did notice that the fan is spinning, but doesn't seem to spin fast enough and it gets pretty hot in my room when I'm playing a game, so I put it on manual fan control, turned it up to 55%, and it hasn't done it at all while that's on.
I'm simply wondering if anyone else is having such an issue, or any issues with AMD's newest drivers? I'm looking around on Google and it seems like there are some, so I'll probably roll them back if I can.
