It's upgrade time, infact it's build a new main rig and cannibalize my two current PCs but that's beside the point. I'm looking into some updated gear, I'm wanting to put together a dual booting Vista / XP machine as my main but I'm curious about putting SLI in the mix. I've never worked with SLI and I'm wondering if it has any effects on using two monitors? I currently use a 7950 GTX with a pair of Samsung LCDs hooked up to it, but I've heard that atleast in Crossfire setups you lose the ability to do dual monitors. Anyone have experience with this?
