Couple of benches from PC Perspective:
Similar numbers at Guru3D ( images since pulled). Full sanctioned reviews up in a couple of hours - including TechSpot's I presume.
Looks like Nvidia have a winner on their hands. Performance/watt, Performance/mm^2, Price (until AMD respond with knocking $50-100 off the 7970's price), excellent 1080p performance, ok 1600p + performance). HD 7970 still the better card in AvP and Metro 2033.
Haven't seen anything much regarding overclocking (1200-1300MHz core doesn't seem to be a problem so far), adaptive V-Sync, PhysX real-time fracture or the dynamic boost/throttle. If the salvage part 670 (and 660 I presume) and GK106 and GK110 follow suit, AMD are going to need to burn the midnight oil, because a refresh with a new coat of paint/clockspeed boost isn't likely to put them back in the drivers seat (esp. on the software front)
