I own a new Macbook Pro 15'', and was wondering, when Snow Leopard comes out, will there be more of a reason to use my 9600M card? Will there big a bigger difference when it comes to editing video and just doing stuff in general?
Updates to the QuickTime libraries might (MIGHT!) add OpenCL acceleration to encoding/decoding of various video formats. Anything else will require changes to iMovie itself, which Apple will likely just throw in with iMovie '10.
