Quadro CX & Adobe CS4 CUDA

[Maverick2002]

CS4 has certain GPU acceleration via CUDA, the most notable for my company being much improved H.264 encoding. It appears however that all of these CS4 enhancements (including the RapiHD plugin) are only available on the Quadro CX. Can anyone confirm? That would be a nice slap in the face - forcing people to buy a professional grade video card just to take advantage of already present hardware acceleration. Of course that's not much different from prior Quadro drivers. Just curious, TIA!
