This is confusing, but all the Radeon HD 4580 numbers going around the web were done using press drivers or the 'hot fix' drivers as ATI called them for the public. These are basically beta 8.7 CATAYST drivers and don't let anyone tell you differently. They include all the fixes found in CATALYST 8.6 drivers and more. ATI just today came out with an update to these drivers and it helped out a bunch...

I updated the drivers to the latest version and the differences are amazing:

So guess what everyone... All the numbers I just did yesterday are already dated... So, when reading reviews keep this in mind ATI has four driver builds out there right now...
CATALYST 8.5
CATALYST 8.6 7.14.10.0590 is the direct3dsoftware version number
CATALYST 8.7 (Alpha I'll call it)
CATALYST 8.7 (Beta I'll call it) 7.14.10.0598 is the direct3d software version number
