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.
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.Did you had any issues with it?
Thats the one i'm looking at, but there is some horror stories about them
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.
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.It strictly for video and photo editing intense Photoshop work
i'm utilizing 96 gig of ram to allow for better crystallization of large files
my 5870 failed and had to plug in my 5770 card in it

Thank you
Thats why i'm looking at 7950
But I hate issues
Hi Matt. Not sure if you came across this thread but sharing it here about the Radeon 7950 which may help. https://forums.macrumors.com/threads/1603588/
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.
