I never had any of those problems you mention, since 10.2 when I bought my card, all the way to 11.3, only a few minor bugs like CCC not remembering video settings (solved in 10.8) and the "pink hue" that's only because AMD changed the default color temperature setting from 6500k to 6600k in CCC since 10.11( I think), just put it back to 6500k and it's back to normal and remembers the setting with every driver update.
I think all the bashing on AMD's drivers are just a huge conspirancy from nv/ intel fanboys, I actually had some real issues with nv drivers on vista, I think it's all made up or that the problem is with the users emselves, alot of people just install on top while having a bunch of bloated crap running in the background, they're just too lazy to even uninstall a friggin' driver properly, some don't even know how to uninstall them , then they come cryin that "AMD driver sux", bunch of morons.
