What Rating Does Windows 7 give the BFG Geforce GTX 275 896mb DDR3 video card?

I just got a BFG Geforce GTX 275 896mb DDR3 448bit video card and i was wondering what rating Windows 7 Give to the gtx 275 just to see how it compared to my old card. i already know about benchmark tests ive looked at them and i know everyone says its alot better but i was just wondering that's all.|||It's a bit dependent on some other factors, so you can't really get a straight number rating for that card on the video test for the Windows 7 rating.
