When I run SLI my 2d desktop is fine, but when I run a game like, World Of Warcraft or Need For Speed Shift, or any in general, even 3d Mark vantage, about 50% of the screen shakes uncontrollably out of focus, like it's out of v-sync or something. If I disable sli it stops... and the game works fine. I just built this, it's my first sli setup, is it that I got a bad card or is the sli setup not right? please help.
