heya.. from wat ive read, people arent getting high oc's at all with xt's unless they use modifications (volt mods etc)..
in the Hard0CP reviews, i saw the sapphire highest (stock ofcourse) at 440/400 (the 9600xt was 580/340), asus was only at 432/387 (they claimed stock speed of that paticular card they received was only 405 and not 412 like advertised), and the standard ATI was 465.75/409.50...
