LtMatt is right,
I went from Nvidia to AMD and in all the games i played with the Nvidia cards the AMD card is not as smooth, although FPS is 60 capped, a lot of games have stuttering.
Skyrim best way to see this go into the skill tree and move along, you will see its not smooth but jerky.
Scrolling in some RTS is also jerky but still 60 fps capped, so dont fully rely on fraps ect.
I will test these drivers soon as i can see if it changes anything but for now as already mentioned Radeon Pro helps with around 80% of my games, its not the best thing in the world to use 3rd party shiz but atleast it helps, it also has a FPS meter in it so you dont have to have fraps open
