Poor gaming performance K8N Neo2 Platinum

Question

I recently installed a new video card - BFG 6800 Ultra and the fps during gaming has dropped drastically. I thought the problem might be the video card so I flashed it to a newer bios, this had no effect. Then I swapped in my old video card - 6800 GT and the problem still existed. I also tried turning off Fast Writes and there was no change. I had my CPU overclocked and tried setting everything to default values, but there was no change. I ran Sandra benchmarks and the CPU / Memory is performing as it should. I would like to figure out if the problem is with a bios setting or the motherboard itself. Here are some benchmarks:
FarCry River Demo:
Before 52.9fps
After 28.8fps
3DMark05
Before
3DMark Score   4425 3DMarks
GT1 - Return To Proxycon   19.6 FPS
GT2 - Firefly Forest   12.9 FPS
GT3 - Canyon Flight   21.9 FPS
CPU Score   4681 CPUMarks
CPU Test 1   2.3 FPS
CPU Test 2   4.2 FPS
After
3DMark Score   2543 3DMarks
GT1 - Return To Proxycon   14.1 FPS
GT2 - Firefly Forest   6.2 FPS
GT3 - Canyon Flight   12.0 FPS
CPU Score   791 CPUMarks
CPU Test 1   0.5 FPS
CPU Test 2   0.6 FPS
Here are my system specs:
MSI K8N Neo2 Platinum 1.4 bios
Athlon 64 3000+
BFG GeForce 6800 Ultra 71.25 drivers
WD 37GB Raptor SATA
WD 160GB SATA
512 x 2 OCZ Platinum Rev. 2 PC3200
Koolance EXOS watercooling (video, CPU)
OCZ Powerstream 520W power supply

I didn't reinstall Windows, but restored to an earlier image. Everything is back to normal.
Crap....I was going to say it was certianly broke and send it to me  ;-)
Glad you got it fixed.
BTW-Why did you go from 6800 GT to an ultra??? So much money sittin' around? I feel your pain.
