I have a asus maximus with 4gig ram, and a e6700. Power supply is 650 watt antec seasonic with both an 8pin and a 6 pin connector for the card. All of these reviews show 3dmark 06 scores around 17000. In windows xp and vista I am getting about 12220. I know the reviewers are using quad core chips, so is that whats bloating the scores?
