Hey all, I have the 6850 in my sig OC'd to 940/1100. It's a rock solid clock, I just spent the day playing BF3 and folding. Problem is, whenever I boot up and set my OC I get strange screen artifacts on the desktop when I, say, scroll down a web page. In game it's perfectly fine but in order to keep these irritating artifacts from happening I have to get up and unplug my monitor and plug it back in. This is with any level of OC, I tried it with 776/1000 (1 point higher than stock) and it still did it. It started doing it after I started using my SSD if that matters.
