I just bought this 7870 about a month ago. I'm having a few problems here and there. I believe they are with the GPU. Sometimes only one monitor turns on at boot. When I play have WOW open on one monitor so I can do my AH when I have time and lets say DOTA 2 Beta on the other itll freeze after 15 minutes. Not with any other games. I was once playing WOW and had a skype window open and a chrome window. The entire screen showed white blocks for about 20 seconds then they went away and WOW crashed. I'm not sure what the issue is everything worked perfectly fine up until a couple days ago. Again its a pretty new card haven't had any issues. Yes I did OC it but by like 10%. (The CPU)
