    Do you use any "special" applications which rely on CUDA or OpenCL?
    I bought a Sapphire Radeon 7950 because i think that Apple will taylor OSX and surrounding applications more and more to OpenCL.

    What applications will you be using it with? Some apps run faster on AMD cards, some on NVIDIA. (Ie: Cinema4D seems to have faster OpenGL performance with AMD, while MODO viewports run faster on NVIDIA cards). Same thing would apply if you were gaming I believe.

    If the horror story is intermittent screen flicker - it was an issue with OSX 10.8 but is no issue in OSX 10.9. So no more flickering.

    Strange behavior is/was that the expansion slot fans rev up after a cold start. Can be fixed by stressing the GPU for some seconds (until the next reboot). My MP normally sleeps, so doing this once every month is not a big issue for me. And the behavior got better (but not fixed) in 10.9.1.

    I guess my initial thought would be the AMD 7950, since it has more VRAM and if you use Adobe CC, it's got improved OpenCL support now (which the AMD is faster at). But, I seem to recall a reviewer upgrading to the 7950 Mac and not being really impressed. So, who knows. Here's a quick little spec comparison from GPUBoss.

    Hi Matt. Not sure if you came across this thread but sharing it here about the Radeon 7950 which may help. http://forums.macrumors.com/showthread.php?t=1603588&highlight=radeon+7950

    Probably inquire the seller or store if you have the option to return the card if it has performance issues. The issues you read in other reviews may be isolated and you never know unless you try out the card.
