Not the worst... for a reference offering and when placed against those 4870 for an extra $20 although no rebate, it might well be a case of; you get what you pay for. Though at the time considered decent on power vs. performance today a 6670 DRR3 isn't all that far off in performance and does it with a pittance of the power. The problem they're not $40, but they also don't have a $30 rebate. That said EVGA should be a gamble which is why Im saying not that worst.
