I just did a 3dmark score, and was suprised at what I got. The cpu seemed fine, scoring 3600, q9300 on stock. However my 4850 only got 3972 on the sm2.0 and 5000 on the sm3.0. I have no idea why this is, ive got the 4850 clocked to: 650/1005. Running on vista, asus maximus, and 2gb of pc8500 OCZ reaper.
