I ended up going with 12 XFX RX 570 4GB and 10 Gigabyte RX 570 4GB.
I have 8GB versions and 4GB version of cards and im getting the same hash rate to not want to spend the extra $100-$150 mark up retailers or amazon is doing.
I will have a total of 5 Rigs each having 6 AMD cards. I will have a 6th rig with 2 cards in it used for testing, modding the bios, etc from the main groups.
The retailer's took care of the 2 limit per household issue for me so I was happy about that.
CPU, RAM, Server PSU and Breakout boards will be here within 10 days now or less.
Ive read the gigabyte gaming uses more power. What have you found since building your rigs? Ive just bought a few waiting for delivery as that was my option or Asus Roy Strix for $100 more
