You guys understand the specs and numbers way more than I do. How much difference do you all suspect there will be from the i7 iMac and the entry level MacPro? Will it be substantial or very little difference? My guess is that is will be considerably faster for video editing and such, simply because the price of each is relatively the same and the MP doesn't have a screen. I would certainly hope that the money I would be spending on just the MP without a screen would be much better than that same amount of money (or close to) the highest iMac. Let me know what you guys think? I'm on the fence between these two models.
