The ray-traced renderer is considered old and obsolete: http://motionworks.net/after-effects-3d-future/
It is being replaced with a more powerful tool .
If you still want to use the ray-traced renderer. Here is the officially supported list of GPU's: System requirements | After Effects
If your card has an older Optix library, it might still work to accelerate the ray-traced rendering effect if you check the "use unsupported GPU" box.
Support for cards with the newer Optix library is coming soon: What’s new and changed in the upcoming update to After Effects CC 2015
so generaly if i just bought a new computer with video card quadro 2200 is supporting cuda? is it the 970x is better to work with adobe ?
After Effects uses the GPU for very little. See this page: GPU (CUDA, OpenGL) features in After Effects
If you don't plan to use the obsolete ray-traced renderer in AE, you should focus on Premiere Pro's requirements if you use Premiere Pro because Premiere Pro DOES use the GPU for a lot.
There are also some third-party plugins for After Effects that use the GPU too. Element, for example. In the case of Element, the GTX 970 is going to be better value for money than a Quadro card would be.
