To put it simply, you can't run dual monitors with SLI enabled. Any app that utilizes OpenGL
will utilize SLI, it's not just for gaming like everyone thinks. 1200watt PS is way plenty, I got
2 8800gtx's super clocked on a 850watt PS and never had any issues with it. What driver
version are you using? I've been running 97 series for the longest time, just went to 169.21
tonite and everything seems to be running quicker now. The 169.44 version isn't certified
so I didn't use that one. XP64 here to, the version number could be different for XP32.
