I'm getting weird windowed behavior (full screen is perfect), and am not sure if it has to do with the GX2, the Quad-SLi, or this whole dual monitor hack I am doing.
From my experience with SLI and CF briefly, windowed mode gaming basically turns the game back to single GPU gaming performance. I've tried it briefly with a pair of 8800GTS and a pair of 3870s.
