I recently got my hands to a PNY 7900GT for very cheap, and installed it to my computer today. I ran 3dmark06 and was surprised of the results. I got 4770 marks, compared to 5986 marks with a 8600GT in the same setup. 7900GT is supposed to be getting SM 3.0 scores at around 2600, this gets 1800. Certainly there is a problem somewhere. However, everything looks normal in the
GPU-Z screen, Which leads me to think it would be the drivers. I got rid of them with DC and reinstalled, but that helped nothing. I am pretty desperate now...
I have tried:
* Reinstalling drivers (169.21)
* Resetting chipset bios (in case the nForce bios had tweaked itself for the 8600)
* Using 2xMolex to 6-pin converter instead of the 6-pin of the PSU (in case the problem was the card not getting enough power)
But nothing has helped.
Any ideas?
