Hi! My american apple contact informed me that my 15", 1.67 ghz, 1 gb ram 128 mb video card PB, turned out to be an 64 mb PB. He was supposed to ship it to me overseas today, but now I have to choose between getting the 64 ASAP, or waiting again for the 128 mb. Im going to use the machine for video editing. Does the GPU size as anything to do with this? On PCs it hasnt, but what are youre thoughts? Thanks!
