Moving from Intel GPU to AMD Nitro+ RX580...Procedure ?

Hi Folks,

So my setup is as follows:

- Gigabyte Z370 Aorus Gaming 5
- Intel 8086K
- High Sierra 10.13.6

I'm currently running with the Intel UHD630 GPU. I had injected the Intel driver within Clover when installing 1st time using Multibeast..

I'm currently using this hackintosh on a movie set for 4 weeks. I need a better GPU to work with Color Grading and movie software, so my budget only allowed me to buy a Sapphire Nitro+ RX 580 8 Go...
