1080Ti is 3% better, but it has 2% devfee and i had EWBF in 1% devfee so, it is marginally better but not by much.

if fee where 1% it would be interesting.

in 1080 (non TI's )  it's the same as EWBF because it is a liiiiiiitle faster, but the 1%more fee kills that difference.

It uses a bit more CPU but not much, 6 x 1080s loads a G3250 Intel at 70% (EWBF is 30-40% CPU usage), so if you had a celeron (unless it is one of the new ones) you could be in trouble but on a dual core intel/amd, perfectly ok.
