Back to the question at hand....
How much lower do you want? You can get a 955 C3 for 140 bucks, and a 1055 for 180. They usually bundle up fairly well with other hardware. Heck, you can get the 1090 for 200 bucks. Serioulsy, how much lower do you want them to go?
At any rate, I think I'm more excited for the Ivy Bridge vs. Bulldozer comparisons than the next generation of graphic cards.
