I'm using Windows 7 Professional x64 with SP1 and the same Nvidia Driver 301.42. My video card is the regular 560 Superclocked version and not the 560 ti(my mistake) which has a bit more power than mine. Though when I overclock it I get almost the same performance as the ti version.
Nice scores though you got most in the 7.0+ range. I'll be upgrading later on so maybe I'll fall in that range too with all components (except maybe the hardrive cause don't need a SSD).
