I'm having HUGE problem's with my HD radeon 6870. I just got a HIS IceQ to go along with my sapphire reference model, both of them are the same card so I figure it wouldn't matter if I got a different brand with a nice cooler. But once I tried to crossfire them all hell broke loose. At first it ran fine booted into windows automatically detected the crossfire everything was fine. Then I tried to run The Witcher 2 on ultra to benchmark it the moment I load the saved data the screen start shaking oddly and then I got a 116 BSOD. So I figure "eh its probably just a driver problem so I reinstalled the drivers and got it to run the witcher2 I even played it for about 30 minutes. After that I thought I was safe but once I tried to run dungeon defender...BSOD. Getting frustrated I did some research and it turns out people were having problems with catalyst 12.3 and crossfired 6800s they were suggested to roll back to the 12.1 drivers so I did that. Now I'm having different problems altogether, when I try to load a game the drivers crash and recover constantly. So I played around with the drivers some more and got it to work...again. So I tried running furmark to stress it and to see if it would crash. It didn't crash but my second gpu wasn't going under any kind of stress it was at 0% load. SOOOOOO play around with it some more (it was 3 AM god knows what I did) and got both GPUs to stress but guess what drivers crashed and recovered. So now I'm its one of 3 things: a bad card, an insufficient PSU, or AMD's **** drivers. I'm going to test the new card on its own to see if its faulty but if thats not it...any ideas?
