Christopher, I'm confused.
I was definitely under the impression that if I bought a Mac Pro, Westmere, and the high end graphics card, 5870, that I would be able to use OpenCL in the development tools, in particular in Quartz Composer. Do I need to buy an Nvidia card to use OpenCL? Does QC support the 5870 for OpenCL development? These should not be complicated questions or answers. Either it does or it does not.
