I just installed my new card (as per the directions on this forum) then proceeded to run 3Dmark2k3. I ran this with my DC client running in the back ground on a P4C 2.4 @ 3.3gig. I was shocked to see that my score of 5071 was nowhere near that of the Nvidia 5900 Ultras that are running 7000+. Any clue as to why? I have the AA and AF set to max so I guess that could have something to do with it.
