Ok so starting from scratch, brand new ssd it took me about 20 minutes to get a mining rig up on ubuntu 16.04 with SA3.
My findings were initially it was pretty much the same as claymore on windows. So technically slightly better as there is no fee. However, then I noticed GPUs dropping out like with Genoil miner.
I then unplugged the ubuntu hd and re-plugged in the windows ssd and that's what I'm sticking with for now.
