I'm putting together a 5,1 build, and had eyed the RX580 as it came highly recommended and native support in OSX. All the links I had for the card have now sold out due to the mining surge, and the ones that have them in stock have had the price go from 300-500/600. From my ignorant attempt at catching up on this forum, it seems the 1060 has driver issues. I'm not to bothered by no boot screen but I do some video/mograph work in OSX so would need it to run relatively decently there. If I buy a PC 1060, do I have to flash it? And is it worth the hassle to get the drivers working in OSX or should I sit on my hands and hope the price of the RX 580s goes down? Shortage has been going on for a few months and the prices just keep rising.
