To start off I have an asus strix rog b-550f motherboard with a ryzen 7 3700x and a rx580. I know that its stupid, and a waste of money, I just want to toy around with it, but I bought a Radeon HD 6450, and I was just wondering for 1.) how to connect it to my motherboard with my rx 580 without it sharing bandwidth or interfering with my rx 580 in any way 2.) Will the drivers work together or will I have to install a legacy driver update amongst with my Radeon software currently?

Also, if I were to have to download the legacy drivers, which one to pick out of catalyst or Crimson?
