Besides, let's be honest, how many gamers really value heat, power consumption and noise before performance? It was always a thing to take the piss out of Fermi for these, but plenty have bought them, simply because of the performance and scaling. Those that still use those arguments either do SFF (where it's fair enough) or are clutching at straws.
I expect that this "6770" will be close to the 5850 in performance, if not better, and the 66xx series will take over from the 57xx series. Same as the 57xx series took over from the 48xx series before that.
