I got it... 1 GTX 1060 6GB give me 598 H/s with 78 watt power consumption. It can be more than 600 H/s if I push the power to 90 watt or higher. So far, it's worth to try.
Click here if you need the miner. Choose one which was uploaded around April. Most people use
ccminer Klaus T 8.21 rev 9. But I got no luck in compiling that version. Then I moved to
rev 7 to make it work.

Very interesting indeed. 78-90 watts is not bad for that hashrate. how long was it stability running?
