chill out guys, let me tell u 1 thing, that 590Mhz clock is no big deal, almost every other card can outdo it with a coolbits tweak, and tell me tell u, the 7600GT core rarely goes beyond 620, NO MATTER WHAT VERSION IT IS, so if u are planning to overclock , be wise enough to get the cheapest 7600GT decent manufacturer, all the cores are same, and have equal probability. I have a XFX 7600GT that runs fine a 615/1620 completely stable day/night. I don't mean to scrap anyone's sale here, I don't have any intention on purchasing a card, but this is a info I should share.
