Looks like after a few minutes, it's settling in around 1.68 kS/s on my rig:

* four 1070s: three MSI Gaming Xs and a PNY reference design
* Gentoo Linux
* mining at zpool

The MSI cards are power-limited to 115W and underclocked by 100 MHz.  The PNY card is power-limited to 95W and running at stock speed.  Total power consumption for the rig is 525W.

With the EWBF miner, I was seeing 1.52 kS/s.  tpruvot's ccminer was running closer to 1.2, so even with a devfee, it looks like you're still coming out ahead.
