Yup! just got it up and running on my 1 4-RX 470 rig.  Running nicely at 40-44 S/s per card (over-clocked & under-volted).  This is WAY up from the 13 I was getting using NHM and while certainly not near the 100 that was initially hoped for, that's a 3x increase that I will gladly pay the 2.5% fee for!

Another thing is that this takes WAY less power than mining ETH.  My full 4-card system only pulls 400-450W running this (and nothing else)... it was using 630-650 with CDM solo mining ETH, so about a 35% reduction is a nice additional bonus!

Waiting a bit to start up NHM for CPU mining. Hopefully there won't be any conflict. When I ran NHM CPU yesterday concurrently with CDM ETH, it completely hosed my ETH returns.
