I just ran 3d mark 2006 on the system in my sig. except only using one of the 7900 gt cards, I got a 4679 using the basic edition and default settings. Does that seem low? As far as drivers and stuff I've only installed the latest motherboard drivers from nvidias site (smbus and ethernet, not ide or nv firewall/active armor)and the latest graphics card drivers. Anyone have some ideas on things I could check?
