Me neither.
More like a dual 570 at 480 clocks (or lower) is what I'd expect.
In any case, my question is this. According to hardware.fr's power consumption measurements of the 6970/50 review, the 6970 consumes as much as a GTX 570 in 3dmark06. Actually the 570 was a tad lower.
It seems very natural for everyone to expect a 6990 with two Cayman XTs but very impossible for a GTX 595 to feature two GF110s. Why?
You forgot to mention that it was about 35watts higher at max usage.
