The X700 series (specifically) seemed to have screen anomolies fron the Hardocp test that was just done on it, and they compared it to the 6600. It seeemed not to matter what driver they used also, but this was only with doom3 AFAIK. but still, it is enough alone to keep me from recommened it. It had small dots in many areas of the maps,and the 6600 was perfect. It was not an terrible eye-sore issue but it was there, again and again. I would hold off on it until that could be explained. Supposedly ATI is working on that issue. I would go with the 6800 series myself, even though I have been ATI for a long time. I just recently got a 6800GT to replace the R9800P in my power rig and it smokes. IQ is also outstanding.
