What drivers are you looking for? I'm running an FP-IN9 SLI (in non-SLI mode) under Vista. I usually let Vista worry about drivers, although I did recently download the 15.51_nforce_winvista_32bit_whql.exe nForce drivers (which don't say they will work with the nVidia 650i chipset, but seem to be fine).
What OS are you currently running? What video card(s) are you running?
(edit) OK, I just noticed it's a few months old...
