If things are working okay, then leave it as it is. If you are having problems, uninstall the AMD Catalyst and Radeon Software, then use DDU to sweep your system of AMD drivers (set a system restore point first) and then perform a fresh installation of the Crimson 15.11.1 Beta drivers, available here.
I suggest you to use DDU to uninstall all amd drivers and fresh install the
drivers. DDU automatically uninstalls your gpu drivers so u wont have to do
it the hard way. Type DDU on google it should be the first one u see.DDU
will ask to use the program in safe mode just click yes. Always fresh
install because other old drivers can mess up with new updated drivers. The
most current one is crimson 16.1.1 hotfix.
