So, a lot of people say that you need a quad core processor, and typically a desktop to edit 1080p videos without hiccups. Now with the new MacBook Pro out with Core i5 and Core i7, would the MacBook Pro be efficient when it comes to editing 1080p videos? Two questions/problems: 1) Hard Drive space would become an issue fast. 2) Aren't Core i5 and Core i7 dual cores, but with 2 "virtual" cores, which makes it four? Would it be safe to say they perform like quad core processors? Thank you.
