If we don't care about resell Price, with my actual market Price i get:

1060 6gb ~ 315sol/s for 225€ (1,4 ratio)
1070 ~ 420sol/s for 350€ (1,2 ratio)
For 1080 and 1080 ti, it's too much expensive for me.

I don't know about wattpower, but I take average stats.

Someone know the eth hashrate of a 1060 6gb ?
