I custom build mining rigs with x6 GTX1070 GPUs.
With the latest version of EWBF's miner you can expect 2450 sol/s on stock cards.
I was able to achieve stable 2700-2800 sol/s on my rig after overclocking the cards. As you know OC is a lottery, however the fact that i OCed 6 cards to roughly the same frequencies makes me believe that you'll be able to achieve similar results.
