For me it still awaits to be seen to how these clock, as we all know the 7000 series likes to clock and generally does it well, the 15% lead the 680 has can easily be overcome with a moderate clock of the 7970, I'm not a fan boys of either brand just im not really impressed by a card with less vram higher clocks out the box and most likely a very similar price range. Unless the 680 has huge clocking potential for me the AMD 7950/70 is still better value if you can call a £350+ card value :-S.
