here is a link to find out ur self how MUCH faster is cuda vs none cuda graphic cards in cs4 and cs5 photoshop
It is Apple fault too.. they supported Nvidia while ago! But some how they force you to use ATI only.
I understand that clearly. But the problem is that Adobe, for whatever reason, has chosen to not leverage OpenCL, which would obviate the need to directly code for either CUDA or FireStream. Under OS X, applications that are written for OpenCL will leverage the gpu for its functions, regardless of whether it is an NVidia (CUDA) or ATI (FireStream) gpu (this is the whole point of OpenCL - hardware independence). Again, Pixelmator smokes Photoshop CS5 in terms of sheer speed. In addition, very few parts of Photoshop CS5 even use the gpu. Most of them are cpu-only; Adobe is stuck in the past when it comes to writing code.
Again, blame Adobe, not ATI or Apple.
