I have now tested both the GTX580 and the GTX680 with Octane. I can confirm that the GTX580 is faster (consistently, about 15% with Octane 1.0 RC3), despite the GTX680 having 3 times the number of CUDA cores. Within a series (5xx or 6xx), speed should be proportional to the number of CUDA cores.
Mmmmm, that's strange. Are you testing on one PC or two? If one, are both cards in the PC at the same time, or are you physically swapping them? Are you using identical camera settings for the test scene?
