The card is able to match and sometimes beat an AMD HD 6950 and tie most of the time with the GTX 570 while costing much less than both. Overclocking was able to increase the core speed from 950MHz to 1010MHz stable with stints up to 1050MHz. The memory speed was increased from 1050MHz all the way to 1250MHz with headroom left, a dramatic increase! When pushing the core speed, the back side of the PWM area became very hot and was likely the reason for the smaller core overclock. The voltage measuring points and BIOS performance switch are nice touches for those looking to push the card although, the PWM heat seems to be the only thing limiting further overclocking.
