It already does both. A lot of Adobe CS4 programs are optimized for the NVIDIA GPUs (Video editing, video compositing, encoding, photo editing, etc). Nero MoveIt, Cyberlink PowerDirector, Elemental's Badaboom all use CUDA (and sometimes ATI Stream) for video effects/rendering. There are a ton more for other computing tasks too (take a look at NVIDIA's CUDA page). Folding@home for example.
