Tom's Hardware, please do as I: buy a new Radeon HD 6000 series card.
Go to the AMD site, select this series to download drivers. What do you get ? Tarammm! 10.10!
Yes! 10.11 does not officially support the HD6000 series!
10.11 is probably the first driver release in history that treats customers of the new series as second class users. Unless you want to run the risk of installing an unsupported Hotfix, which, by the way, does not solve many of the problems HD6000 series users are complaining about.
The 10.11 release focuses on HD5000 series. And the Hotfix 10.10e too; the rest of the features listed in 10.10e is a copy-paste of the 10.10d release.
Of course, there is a 25 million HD 5000 series market to cater too, but... treating HD6000 users like this is bad PR. At least treat users equally!
Going out and rush MLAA support for HD5000 series when users weren't even expecting it, is doing things the wrong way around.
