Scawen: Be aware also that Vsync can cause issues on SLi systems. Best case scenario, Vsync just doesn't work, worst case, all timings go to hell. I'm not sure of the exact cause of this, but I will do some research and give you any useful links I might find. Just wanna give you the heads up. I know Vsync looks good on paper, but I have very few aplications where it actually does any good. I never noticed much tearing in racing sims anyway... I'd rather rely on some minimum sleep value to give the cpu and system a breather.
