I've been playing around with the new card and comparing it to my 7970s. With the exception of MW (DP) the GTX 1080 outperforms the 7970. In some cases by wide margins and in others not so much. This will at least give you some numbers for the GTX 1080 so you can compare it to whatever card you have and help you decide if a upgrade is worthwhile. The 1080 definitely performed better than my dead GTX 780 so that upgrade was worthwhile.

GTX 1080 - clock rate 1911-1965 MHz selected by card and it changed with project
7970 - clock rate 1100 MHz - selected by me

Both cards in identical I7-3930K machines with 12 threads available to the GPU.

GPUGrid - both cards tied at zero credits They have to change the program to match the architecture of the new NVidia cards and they can't do that till they get one.

The number of simultaneous WU were chosen to get the cards to 100% loading.

NOTE: it is possible the GTX 1080 would perform better on a PCI 3.0 mb but you can't prove it by me

Both cards were "optimized" on Collatz.

I didn't run Asteroids or Einstein and I damn sure didn't run Seti ... I only run Seti when I need 100 hours for WuProp stars!!
