Apple hasn't released a product with an NVIDIA GPU for years. Also, driver support for NVIDIA GPUs on MacOS is not very good compared to AMD GPU driver support on MacOS.

While with AMD, the drivers for RX460/470/480/560/570/580/Vega are already built-in and you only need to correctly inject them. You just need to use one kext (kind of a driver in Mac) called WhateverGreen (to be fully correct you also need Lilu, but you almost always have it anyway on your Hackintosh). It works without issues and is generally preferred among Hackintosh community.
Another thing is that tonymacx builds are generally bad if you want a stable and easy to build Hackintosh (at least as easy as it can get). They are being sponsored and their choice of hardware is strongly biased.
