I am saying I bought HD6970s in CF because they were better bang for the buck than 2x GTX580s in my mind ($370x 2 vs. $500x2). It was great that AMD gave me a dedicated gaming chip without GPGPU compute features I didn't use. I knew that GTX580 was better in compute. If someone needed those features I'd recommend them a $350 GTX570 for example.
How come so many AMD users are only now touting compute performance as a key advantage? I bet they also purchased the awesome HD4870, HD4890, HD5850, 5870, HD6950, HD6970 cards in the past. If compute performance was so important to them, they would have been running NV's cards since 8800GTX. That's my point. So there isn't a lot of sense in trying to defend AMD here.
I actually saw much of the same when HD5870 was losing in Tessellation heavy benchmarks (Crysis 2, Lost Planet 2). When HD7970 launched and beat GTX580, suddenly Tessellation became important. Again, another inconsistency on AMD user's part that I find rather odd.
Now GTX680 beats HD7970 by 40% at 1080P in Batman AC with Tessellation.

Again, isn't that better for us gamers? 2.5 months after HD7970 launched, we can buy a $500 card that's faster than a $550 card when key DX11 features are enabled.
I wasn't defending GTX580 when that card consumed more power, cost more $ than HD6970 because it had GPGPU features only to turn around today and start defending HD7970 vs. GTX680 because HD7970 is a better compute card but a worse gaming card.
It seems this time GTX680 is more efficient for gaming. GTX680 is a dedicated gaming chip just like my HD6970 cards are. It also costs less than the 7970, has a quieter cooler and consumes less power.
HD7970 this round is like GTX580 last round in that it has plenty of GPGPU compute, consumes more power, but now it's actually slower and costs more. Why would I be defending AMD in that case? It seems NV now offers everything that made HD4800/5800/6900 series great - higher efficiency, lower price, more features and this time actually faster performance.
Either way, I think if this puts downward pricing pressure on AMD, that's also a great outcome because of GTX680.
