Hi,

If you are not really into tweaking hardware, Go for Nvidia cards.
The Rx 570/580 5 Card rig was really Tricky to get going the way i wanted it...
The 3 gtx 1060 6gb cards were really easy and Type of set an forget.
Furthermore the gtx cards, If oc ed well, need way less power.
If that is an issue for yOu?!
