So today i upgraded from hd 6750 to 6870! I having problems running diablo 3 beta, it does these weird things on the game blinks different colors in certain spots, Other then that all other games is running smooth. Wow, cod:mw3, sc2, BF3 ultra fine.
Please help me fix this, also downloaded the recent update for it.

I haven't had that problem, but I wouldn't worry if it runs everything else smooth. Remember, it's a beta for a reason.

It'll be fine. I just hope their servers hold up.

Actually after playing for awhile on sc2 is doing the same thing, blinking different colors at time. I installed 64bit software since i am running windows 7 64 bit ultimate.

Drivers are up to date? If so, you may have gotten a faulty card. Test in more games.

Yeah drivers up to date, I test on COD:MW3 no problems, the video cards has two 6pin power connecters. PSU gave me 1 6pin connect pci and 8pin connecter pci but has two 2pin separate can be used as 6pin. I connected those two, u think that might be the problem?
