definant I'm new to the forum as well. Just a few questions on your rig though because I've been thinking of upgrading and going single GPU again.

I currently run an XP rig with two Nvidia 7800's in non SLI mode, with a 1920x1200 connected to each. Prior to twoboxing, the second monitor displayed ventrilo, web pages, etc.

Now when trying to two box I can get a window on each screen with Maximizer. I'm supposing here that they run on the different screens (though when starting the second window it flashes briefly on the main screen before coming up on the second. However fps takes a nosedive

Am I losing performance on that versus going back to SLI mode and making the single "seen" GPU dual-head? Am I beyond the capabilities of Nvidia here wanting to split one to each GPU?

The reason I hopped off SLI mode was that it caused some issues running things outside of games. It's very nice being able to do nearly anything on the second screen no matter which game I'm in.
