I have a ATI X800 XT and last time I looked at the comparisons, even though the 7800 Nvidia is a little more advanced (supports HD lighting or whatever), it was still similar in performance.... And I wasnt happy with my FPS being in the low 20s and 30s outside...

I know it is suppose to be a next generation game but back when I bought Oblivion my X800 XT was running $300.... For $300 fucking dollars you should get more then 20s and 30s FPS IMO.
