Just my 2 cents. I just upgraded from a 9800GTX which was about 3 generations behind the 480 and now have an ATI 6870. The jump in performance between the two cards is significant when single boxing but I have to say even being 3 generations apart the jump in fps is not that huge in "most" places. What it did enable me to do was pump up the quality settings a bit more BUT again this is really only noticable when I single box.
