On my main rig, each month I have been downloading the new drivers, uninstalling the old drivers, rebooting, and installing the new ones.
But, on a spare/server rig, I got the desktop notification from the catalyst control center that there is a new update available, so instead of ignoring that and doing the above steps, I just clicked the button to have AMD do the update for me. It did the whole thing and was very easy. I may just do that in the future on my main rig, since it's so easy and not a bother at all, and I don't think it's necessary to go through all the cumbersome steps since it's not like I'm switching between AMD/Nvidia each time.
