No, not right! I want to know which card os good for all of the adobe software. Not only after effects.
Looks like your post was moved to the hardware forum now.
After Effects doesn't use the GPU for much. The only thing in AE that requires CUDA is the obsolete ray-traced renderer. So I wouldn't worry about that. The three effects that the current version of AE uses the GPU to accelerate will use Open CL (and Metal, if you have a Mac) on AMD cards.
Premiere also uses Open CL on AMD cards, but I'll let the Premiere folks talk more about it.
And is the new feature of the realtime viewport look in the new cinema also using CUDA?
