Sorry to reply to my own thread
I am also experiencing poor performance with this card. I previously had a XFX 512MB 6200 running in the PC which performed better!
With the previous graphics card, I could spin the globe in Google Earth with no stutters, it was very smooth. With the 6800GT, it stutters every second or so.
I have made sure my AGP aperture is 256MB (in the BIOS) and my system is beefy.. so i can't understand why the graphics runs slower! Can anybody suggest any other settings I can change to get the card running properly?
Cheers - Toff
