I was just wondering if my thought that potentially with the unpcoming OpenCL and Grand Central could we all turn a Mac Pro into a mini render farm. What Grand Central and OpenCL will do is efficiently separate and allocate tasks to various cores in CPUs and GPUs. So load up the four spare PCI Express ports with graphics cards on the cheapest octo-core and you have one machine capable of doing the work of 2 or 3 machines. Unfortunately I fear, the reality is probably not at all that exciting
