I have 2 7900 gs in sli. The system is new by a few days. Things seemd to be ok, though I have had a few windows issues. I loaded call of duty 2, clicked the sli option, the game went extremly fuzzy then it was like my monitor just shut down. Since then, I get some fuzzy action on the screen, usually on the sides. It not terrible, but you can easily tell its there. Sometimes it appears as the whole screen get slightly bigger and smaller. I used drive clean, put the drivers back in, same results. Opinions?
