AMD and NVidia card combo?

[Clayf700]

I have a GTX 1080Ti and love it. Although I'm stuck on High Sierra due to the lack of NVidia support, and would love to upgrade to Catalina. With Nvidia formally announcing they're dropping CUDA support I was wondering if it's possible to purchase an AMD card to use for macOS, while still using my Nvidia for windows?

Possibly. But you will have to do some research to find out how to "disable" the Nvidia card while you are running MacOS. I hear that it is possible to do that, but personally I have no idea how to.

And of course you will have to make sure your power supply is capable of supplying power to 2 power-hungry graphics cards, and that your case can accommodate 2 graphics cards.

Good to know. Would you happen to know if it's possible to use the two cards on the same set of monitors?

I have no experience, but I would think it should be possible if your monitors have more than one display input. Just connect the inputs to the cards per your requirements and switch inputs on your monitors as necessary.
