I realise this is not the specific forum for this discussion, but I find that the most knowledgeable people hang around these parts so it's worth a shot. There are many threads on these forums where people ask, "What computer should I get to do xxxx". The nearly automatic responses are usually along the lines of, "Don't get so and so if you're working with graphics because it has integrated graphics / rubbish graphics card". The question for me, however, is just which applications actually utilise the GPU to perform processing? As far as I know the only way to do this in Mac OS is via OpenCL so I assume that my real question is which applications actually use OpenCL. I believe that Final Cut X uses it, but I am curious if this is correct and if there are others? Does any one know of a definite list?
