Greetings everyone.
Long time lurker and just built my own rig with the new NVidia cards.
I went with two GTX 970's as they are readily available, in my budget, power efficient, and easily found in reference design.
I haven't seen any benchmarks around for these cards, so here is mine.

I feel it is rather impressive for NVidia hardware and furthers a lot of the claims that these new cards are pretty sweet.
Setup is Ubuntu 14.04x64 and I'm using the official NVidia 343.22 drivers and cudaHashcat-1.31.
xorg.conf includes:
At the moment I am very mildly overclocking with (note: cannot run as root):
I found that a higher clock offset and/or any transfer rate offset increase resulted in cuStreamSynchronize() 700 and/or 702 errors. Something I am still trying to wrangle in.
