Summary: This turned out to be a great card. The voltage is unlocked and I have it overclocked to 970 Core and 1520 Memory @ 1.250 volts. I sat up a custom fan profile and even with that overclock it never gets over 80C.
Summary: I'm using this card in crossfire with my HIS ref 6950 flashed to a 6970. It's working great! My framerates doubled in BF3 ! In 3Dmark11 my score doubled. Was 5900, now it's 10290. The 6970 is running under 60°under load with the fan speed at 70%. Same as my 6950. No problems with my Ebay purchase!
Outstanding performance coupled with rock-solid reliability
