Recently crossfired my 6950 dirt 3 with another 6950 dirt 3 both cards alone score 5100 in 3dmark11 and crossfire they score 8500, seem low? I have uped the page file space, turned off ulps via registry and bf3 is set to max settings and it almost seems like it runs smooth, then gets real laggy, and it continues to do this, havent spent a whole lot of time checking things but it almost feels like i have high fps then low fps, with all settings maxed, i have cat 12.1 drivers with cap 12.2 cap 1, is my 3d mark score low? What seems to be the issue here? I have an intel i5 2500k currently running at stock, g.skill rip jaw series 1600, asrock extreme3 gen3 corsair tx650m psu.
