Restarting a hack to do it vanilla

I have a working hack that I made about 2 years ago. It's dual booting High Sierra and Windows 10 right now.

I used tonymac's guide including unibeast and multibeast. I got tired of waiting for nvidia to put out mojave drivers so I just bought a MSI Vega 56.

I've been unable to get the Vega to work at all right now, when I remove nvidia drivers and the 1070 and replace it with the Vega 56 and boot up I just get blank screens.

In the process of trying to figure it out I've thought maybe I should do a proper vanilla install. Has anyone got any experience, tips, guides, or suggestions about going about this?

Sorry it's been a while since I set this hackintosh up and am trying to get re familiarized with all the ins and outs.
