While building a Hackintosh, one of the Graphical Processing Unit (GPU) that I chose was the Sapphire Radeon Pulse RX 580 8GB due to the multiple onboard video connections. The GPU works great under Windows (no surprise there) along with Ubuntu and macOS. Versions older than macOS Sierra were accessed in a virtual session using VMware Fusion while the others were booted with Clover Bootloader.
