Here is a guide that I think a few are looking for to help them open the door to other options outside of Nvidia Kepler GPUs like the GTX 680 that are rather old and quite expensive.

I'm going to do my best to break this into two sections, one about getting boot screen with a stock PC RX 580 with no flashing and a second section for getting the RX 580 working in Mojave 10.14.5 as these really seem to go hand in hand.

The Mojave portion of this guide will only work for 10.14.5 due to AMD...
