So, my Gigabyte 6970 does something weird but I don't know if my card is defective or if its a driver issue or what. In 2D Mode after BC2 or 3DMark Vantage, I get little green pixles that flicker all over the dark areas of my screen (wallpaper / web pages). They go away if I reboot the computer or change the screen resolution. The only time I have noticed these green dots / pixles in a game is in Bad Company 2 at 1920x1200 in some of the fog around the edges pretty heavy. I can only seem to replicate this problem when running 1920x1200. I tried to take a screen shot of it, but it does not show up in screen shots. This makes me think its a connection issue with the monitor not a video rendering error. What I don't understand, is why would the connection issue only happen after BC2 / 3DMark Vantage and not go away in 2D mode until reboot? I have a 28" monitor that only has a HDMI port. I usually use a DVI>HDMI cable that came with it, so I tried just a regular HDMI cable and the problem actually seemed a little worse if not the same. I'm not sure what else to do or try. I know its not the monitor because it never did this with my 4870x2 video card that I had right before I got this card. I did use the 6970 bios for about a week on this card, but when I notice the green pixles I put it back to stock just to be safe for now. I've tried reinstalling drivers and nothing seems to make a difference. I don't think its any core/memory damage because the pixles show up correctly in screen shots and all games / furmark / 3dmark look fine. 
sorry!
