Unless I'm mistaken, but doesn't SLI disable multiple monitors?

That being the case, what point would there be to a second video card with SLI?

Since XP doesn't handle multi-view properly(only horizontal/vertical span and clone), I'm wondering why then if you're using XP would you want a second card at all, unless you can span a desktop using two monitors connected to two different physical cards (which I likewise think XP can't do).

Am I missing something here?
