Ah... nothing really interesting to see here people. 1080Ti is still the king. 
Yes, I love my 1080ti's
But too expensive...
1080ti is the best balanced with the price and powers solution market has now, if you can grab one for $700 it would be basically a stealer!
see for yourself :
1. performance wise one 1080ti is equivalent (rough) for two 1070 and three 1060
2. 1080ti eats like 250-260W, 1070 - 130-150W, so 2 of them will be 260-300W, 1060 - 100-120W, so 3 of them will be 300-360W - who is the king? 1080ti!
3. the price for 1080ti is $750, for 2x1070 is $850, for 3x1060 is $950. who is the king? 1080ti!
IMHO the 1060 3GB is an awesome bargain if you mine a bunch of algos (not just ETH)... you can get them for $189.99 each at this time. I bought 20 pcs of the EVGA Superclock 1060 for this price recently.
I have a large number of 1060 3 GB (various brands) in my mining farm and I'm very pleased at price / performance / time to pay-off.
