Even then I still like nVidia because they're at a significantly lower TDP (670 takes 60 fewer watts than the 7970). It's a bit odd because they're both on TSMC's 28nm.
I fear for AMD if the 660 puts up as much of a fight at it's price as the 670 does.
Maybe AMD catches up with their new CPUs? But they're a node behind and Intel's got a whole new chip next year.

The reason the 680 is smaller with a lower TDP than the 7970 is that the 680 loses by a large margin on GPU compute and it is total crap for DP GPU compute. Since gpu compute is insignificant for gaming at this point in time the GK104 is better for a user who only cares about gaming.
Peak Compute performance;
HD 7970: 3788 SP-GFLOPS, 947.2 DP-GFLOPS (1/4)
GTX 680: 3090 SP-GFLOPS, 129 DP-GFLOPS (1/24)
Nvidia did exactly this for fermi. GF100 was a beast for compute but was hot and massive and lost against AMD for gaming.
GF104 cut a lot of compute performance and went head to head vs AMD.
GK110 should bring back the compute crown for Nvidia (their Tesla business depends on it) but I suspect it will be at the cost of gaming performance.
