I've been playing around with a 7800 GTX recently and it consistently scores more than twice as high in 3dMark 05 and 3dMark 03 than my 6600 GT does, and its ability to play games at high resolutions with AA and AF at max settings without any slowdowns/choppiness whatsoever is thoroughly amazing. Since you're waiting 2 to 3 months anyways I'd say save up for a next-gen card like the GTX or even the GT...the prices should be down a bit by then, especially if ATI manages to get its next-gen card(s) to the market.
