I have both monitors plugged into the primary card, I was just testing the idea of plugging them in differently. As for sli running only in full screen, I didn't know that. Even when a game is windowed though, it runs just fine and the overclocks are correct with both cards. That is of course, only when I'm not multitasking. Lastly, you're brilliant. Turning off hardware acceleration seemed to do the trick and fixed the asynchronous overclocks. Thanks!
