First Hackintosh

So I’m contemplating trying to install BigSur on my PC. Motherboard: Asus z390A CPU: i7 9700k DDR4 RAM

My question comes down to GPU. I have a MSI 1070 and was curious how all this would run off of the motherboard graphics. I assume I couldn’t get 4K at 60hz.

Anyone else setup similarly? Would I need to unplug the 1070 to get this to work?

Thanks
