Re: GTX 285 and PCI-E 8x....
It might be slightly low... but it's not that far off from where it should be for your setup. My '06 score is in my sig and our systems are pretty compairable... I probably score higher because of my CPU overclock as it looks like you have your video card clocked almost the same as mine. I bet if you ran your CPU at my speeds (as you have the same CPU) you would probably get around the same score. I'd say you are fine.
