lol no it's not 80% more hash where you get that? a 1080ti is 80% more faster than a 1070 not 1060, maybe you are confusing with the 1080s
i used 2 recources for the comparsion:
whattomine.com
1060 - Ethhash: 21.3 Mh/s
1070 - Ethhash: 30.0 Mh/s
1080Ti - Ethhash: 35.0 Mh/s
https://www.nicehash.com/?p=calc 1060 - DaggerHashimoto: 20.13 MH/s
1070 - DaggerHashimoto: 28.69 MH/s
1080Ti - DaggerHashimoto: 35.00 MH/s
are both pages wong with the Ti?
for my 30 1060 the result is nearly as stated there.
