Hi,

I have 1080TI (http://mylifegadgets.com/GTX1080TI) doing about 915mh/s skein, about 10-12$ per day. Also i have GTX1080 (http://mylifegadgets.com/GTX1080) doing about 7-8$ per day. Both use the same 180W from wall, so i would suggest TI-s but if you get really low price for 1080 i would go with it.
