Just returned my Vapor-X 7970 for the Vapor-X 7950.
I could OC with stock volts (1.256v) to 1200/1600 however you can get the same score on benchmarks and game performance with the 7950 version..
Safe yourself £120 and buy the 7950, perhaps save up for crossfire in the future when the cards prices come down even more??
How is this at all useful or relevant to the OPs problem?
