I have a Mac Pro 3.33 single, but just picked up a Mac Pro Dual 2.6....
I basically use my machine for video editing in iMovie, and CAD/Rendering. I know the rendering will increase w more cores available, but I am wondering if iMovie can take advantage of the dual processors or not. If not, than me 3.33 will be faster. Tried googling but most answers were from forever ago, with the old version of iMovie HD.
