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 ?
Everyone is going for the 1070 because of density.
You have to split PSU, mobo, RAM , CPU cost on GPU's. Less GPU with the same power have more density
Anyway 1060 are very good, if you find a good offer you should buy them
