If I am switching between Rx-xxx graphic cards, do I need to uninstall/re-install the AMD graphics driver? It seems that it should simply be able to recognize which of their cards I have at boot time since the driver files are identical.
It's a good idea to always make sure you have the latest drivers from the AMD site.
Actually, I always have the latest driver. But I move cards around from system to system as I benchmark and just wanted to avoid having to go through the uninstall/reinstall process all the time if it wasn't needed. I was under the impression that AMD used a unified driver that recognized the card automatically on boot.
