I am running 5 RX 480 on a windows 7 on a nanopool. A rough calculation is that I make $150 a month from all 5 cards. My investment into it is about $2000 and my ROI is about a year. Are my calculation right??
You will never ROI when ETH goes PoS.
etc will not go pos from what i've gathered, also with 5 x 480 at 30MH each it seem a bit wrong to do only $150 a month if electricity is not very high
