180 watt for 29 eth and 780 sia is bad
rx 480 does around 26 eth and 470 sia for half the price , that is if you can find any rx 480 lol
...Now I stop with (31.6eth+630sia)@2050/2400@0.975v...
What brand & model 1070 did you buy? I can't get anywhere near those OC numbers without artifacts and forced reboots. Best I've been able to do with my MSI Gaming X 1070 is 1950 core, 4465 memory, and 1031mV core voltage.
