This one is tricky for me. Right now I have a Nvidia GPU and an intel CPU that doesn't have a integrated GPU. I'm about to take my old Nvidia GPU out and put a new AMD GPU in. Do I need to download the AMD GPU drivers BEFORE taking my PC apart? Is it bad if I download AMD GPU drivers while an Nvidia GPU is still running in the system? How does one change his GPU in this situation without messing things up?
