Poor performance with 6800GT PLEASE HELP!

[husker4life]

My system specs:
athlon 64 3000 (stock)
evga 6800GT (stock) 60c idle 70-75c when playing games
asus K8N-E deluxe nforce 3 250gb mobo
1 gig XMS corsair memory
120GB WD HD
Lite-on DVD/CD RW
sound blaster audigy 2 zs
antec SLK3700 350w
Windows XP SP2, directx 9.0c, Nvidia 61.77 forceware drivers

Farcry version 1.2 (max settings no aa/af) running fort demo using bench em all program
1600x1200 38 fps
1280x1024 49 fps

Doom 3 version 1.0 (high setting no aa/af) running timedemo demo1
1600x1200(vsync off) 44 fps
1600x1200(vsync on) 32 fps
1280x1024(vsync off) 51 fps
1280x1024(vsync on) 43 fps

Im not happy at all with those numbers compared to computers with the same specs as mine, its running about 30-50% less then some benchmarks ive seen on the internet. I did switch video boards during the build process, i went from a 9800 pro to the 6800GT and when i got the computer i still had an ATI directory on the hard drive which is not good. I ran driver cleaner and cleaned out the ATI stuff but i still get the same crappy fps numbers. Im not sure what to do at this point any help would be greatly appreciated.

Do you have Forced refresh rates in your Nvidia Drivers?? I have a verry similar system to yours, almost identical, although your A64 is a tad faster in games than my older P4. I can get 47 fps average in timedemo 1 with Vsync @1600x1200 and 57 fps average without Vsync @1600x1200. I was experimenting with refresh rates, my monitor can to 100Hz at 1024x768 and 85hz at 1280x1024, but the game sets the monitor to 60 hz when the game is running. So i tryed to force refresh rates through the drivers, lo and behold my frame rates in D3 dropped by 10 at every resolution!!! I think this is because D3 has a game pace or tic as carmack says of 60 hz. So chech your driver settings.

Where in the in the driver setting can tell if the refresh rates are forced or not, im running 1280x1024 at 100 hertz.

My refresh rates are application controlled
