N2DCRYPT: At this time our focus with ePIC Boost is on our 570 16GB card.
Lunobird: I am looking at some data right now that is showing over the long haul we actually mine C31 faster than a 1080ti with our 570 card. I need some time to get more info on the stuff I am being told but this looks promising.
XXCSU: Our focus right now is on Grin but I will see what we can do about getting some testing with other coins.
