The GTX470 isn't their highend, its their second tier highend. And why can't you believe it? If clocks are but 1 of the 2 reason the 512Sp part isn't available, why is it so hard to believe lower clocked secodn tier part? ATI is doing with the 5850 vs the 5870. The 5830 will have even lower clock than the 5850.
