My GTX-1080 is getting a little long in the tooth, I'm thinking of going all AMD on my Linux Mint gaming rig here, but…is there anything I need to do or install or uninstall to switch to an AMD card from an Nvidia one?

I've never done this before on a Linux system; I've got my Intel/Radeon laptop, and my Ryzen/GeForce desktop and that's most of my Linux experience.
