GO here to find the latest AMD drivers: Chipset
Plug in the info on your GPU and there you are. If you get a message from the driver that a newer version is available, but you have verified that you already have the latest version installed--ignore the update message. Always go to the link above to check on the latest driver release--also, use your eyes--since AMD drivers follow a progressive numerical scheme, 18.12.3, for instance, is newer than 18.12.2. If something as simple as this bothers you a great deal, maybe you *should* check out nVidia...;)
