The labelling might be a bit confusing but this new driver is for all AMD cards from the Radeon HD 7700 series and higher, including the brand new RX 480.  It adds the Radeon WattMan overclocking tool, a Crossfire Toggle for easily switching between multiple GPU and single GPU mode as well as numerous other new features which arrive with the card.  The Release Notes do not detail too many game fixes, this release is more about adding new features to the software suite.
