Im getting 10K with my E6300 and 8800GT 256 under Vista64, a little higher under XP. I am not overclocking my video card either.
Id say your score is very low, there must be a problem somewhere. Did you do a complete driver cleaning before installing the new card?
No I didn't I still have the Nvidia drivers on it... I'll do a complete unistall and see if that works...thanks
