Edit: As far as the 580 goes, it gets 197.6 GFLOPS DP - yes, even faster than the Titan and faster than the 680 which only has 128.8 GFLOPS DP, and the 580 costs less. You'll also get better SP compute results from the 580 than the 680.
JPM: Maybe there is one more angle to look at, power consumption per GFLOPS?

The CC describes the GPU's abilities, and the researchers use this to determine the GPU type. The top CC2.0 GPU's (Geforce GTX 590, 580, 570, 480, 560 Ti (448), 470, 465) are less power efficient than the top CC3.0 GPU's (GTX690, GTX680, GTX670, GTX660Ti, GTX660, GTX650Ti, GTX650) making the CC3.0 cards preferable. The GTX570 and GTX580 are roughly as powerful as the GTX660Ti, GTX670 and GTX680, but being less power efficient and an older generation they are slightly down the recommended list.
