Is anyone buying 1080Ti for mining only?
To me that doesn't make sense as there are cards that offer more mhs per $ invested. I guess you are buying 1080Ti for gaming and mine when you can?
ya haha i think your missing some factors, as 1080ti will win if your LONG, everytime

sure you can get better "hash per watt" but you will fill a WAREHOUSE to have the same hashpower as a 1080ti army

you will build x3 as many rigs to equal your farms capacity in hashpower if you use 1070's
you will max out your location and/or end up paying for space using 1070 over 1080ti
put THAT into your $$ calculations ;p
another factor: soloing
You CANT really solo on a 1070 rig for too long, you dont have enough hash :/ but you CAN on a 1080ti rig, i do on SIGT and have made a KILLING still today, no 1070 rigs can still solo at this point (unless 10+ cards)
my 1070 rigs mine inna pool ;p
1070's WERE king, but times change man, especially since 1070 prices are STUPID now (i paid 400USD for my 1070's brand new form newegg, they are WAY higher now)
