Really no point in this miner since with Silentarmy V3 on linux you can get 40Sol/s currently with the 290/390. With some tweaking OC you can get 45Sol/s probably. So with his 5% dev fee, you will most likely net the exact same amount.
I doubt Claymore can get more than 40-50 Sols with the RX 470/480 which you are currently getting with Silentarmy V3 for linux.
since we don't all use Linux we need the Claymore miner now more then ever for WINDOWS!
that's what i'm seeing too...linux miners got the edge in mining ZEC right now, Claymore will hopefully level the playing field.
