Would Adobe please add the Quadro K4000 and the GeForce GTX 780 to the supported card list for CS6. THANKS
This is a user-to-user forum where people come to help in their spare time. If you want to officially request something from Adobe, you have to file a feature request. If you do, you request can be officially tracked. If you just do a forum post, it really won't help you at all.
Please be aware that After Effects will most likely work just fine with either of those cards. AE uses the GPU for very little - see here. Of course, some third-party effects do use the GPU, but they don't require a white list of cards, so you should still be good.
Note: these cards are already on the list for CC. CS6 is the old version of the software.
The fact that they are still releasing updates for CS6 (another one is meant to be coming next month) is really benevolent on their part and not something every software company would do. However, the updates they are making are mostly to fix bugs. They are unlikely to add functionality to old software.
