I had 2 9800 Gx2's, real world performance the 2-8800gtx's I got rid of were better.( I know the memory bandwith stinks thats why I'm back to the 8 series. ) Know I have 2 8800 ultra's. I can't find and proof that the 280 gtx is better than the ultra so I'm staying with the tride and true. Flight simulater test and the ultra won...that is the only vs. testing I have seen.
