Using the 1600P Tom's results it's 20% faster @ 1600P. Now take a look at the historical increases seen there -

1080P 8XAA = 84%
1600P 4XAA = 64%
1600P 8XAA = 133%!!
100% increases are long gone, that was 8800GTX. But there is temper and there is jump in a vat of ice water temper. 20% ? Really ?
Ya, that's why I like to revisit reviews 6-12 months later to see re-assess how the newer generation of cards performs in more modern games. If we just went off launch TPU reviews of GTX480, the performance increase over GTX285 would have been very underwhelming. Put a GTX285 ~ GTX460 1GB in a modern game and GTX480 will
easily lead by 50%+.
However, due to consolitis, it looks like Metro 2033, Crysis 2, BF3, Witcher 2, Dragon Age 2 are as demanding as things are going to get in the near future, at least until GTA5 is out this year (Metro 2034 got delayed into 2013 I believe).
So unlike initial reviews of HD5870/GTX480 that didn't allow those cards to truly shine vs. their predecessors, GTX680 is put in the best possible light right now since the games where we need the most performance is where GTX680 is nowhere near 50% faster than GTX580. So if it can't beat GTX580 by 50% now in the most demanding games, I doubt it will come up with some magical boost later.
Having said that, I still think GTX680 is an upper mid-range Kepler card: 256-bit bus @ 192GB/sec, 2GB VRAM, not a 400mm^2 die, neutered DP performance. In that regard its performance is in line against GTX580; its naming and price are not. :biggrin:
I think you just have to wait until GK110 or get a high overclock on 2x GTX680 (1300mhz+) before you can ditch 3x GTX480s @ 580 speeds and still get a nice 40-50% performance increase.
