Hey guys and gals, I'm going to purchase a macbook pro soon for video editing. I use FCS3, adobe cs5, and someday fcpx and motion 5 when I hear it improves. I don't have the hugest budget for a computer right now, so I'm looking at the 13 inch macbook pros. I can get a refurbished mbp i5 or a core2duo for the same price. I can get the i7 for a little more. The core2duo has the 320m gpu which may be better than the HD 3000. So my question to you all is this: For video editing including work in motion, is the i5 or the core2duo better all things considered? And, would the i7 make much of a difference for video editing+motion work in comparison to the i5? Thanks a ton macrumors!
