I know very well that the overclocking is not a certain thing, it depends. If my info about the overclocking misleads any of you, that was not my intention or question. And I also know(no offence) that both cards are good. The actual question was,
Which one is better IceQ X2 or the Vapor-X.
And what about changing the Vapor-X's connection 6+8 pin to 8+8 pin.
