Thanks for sharing your experience with us @cryptochron! We are expecting to start mining with one rx 580 (should arrive soon) at the start and maybe more if the stock's arrive and if we have the money for it :p I'll probably test claymore and nicehash right at the start since it's the cheapest way to start mining!
We'll test everything OC and bios mod and then report our experiences back to you guy's! And soon we will have some help from a friend who is an expert with Linux so we will proper review ethos and if I get some good results I'll tell you everything the expert did so you can test for yourself :) keep posted on the blog and we'll post everything very soon! If you could share it so other interested people know we would be so thankful :D
Welcome bud, if you need more info or any help check out this awesome article tutorial on the rx 580. This should be enough to guide you to the promise land.
