Hello everyone! I've got a problem. I want to buy a macbook pro for on the road video editing, but I cannot seem to make up my mind which one I should choose. The price range between the 13'' and 15'' is pretty big, so I don't know whether it is nescessary for me to spend that extra money. I am video editing with final cut pro and I use adobe after effects and photoshop, and I would like the system to run as fast and as smooth as possible, yet still be laptop. So the three that I can't seem to choose from are: 13-inch: 2.3 GHz (dual-core) 13-inch: 2.7 GHz (dual-core) 15-inch: 2.0 GHz (quad-core) And which ever laptop I choose, I will change the hard drive to: SEA MOMENTUSXT 500GB SATA2 HDD +4GB SSD (7200 rmp) and RAM memory to 8GB. So anyways, even with the things I am going to add to the laptop, will I still have to buy the 15'' one because of the processor and two video cards (even though I know that video cards are mostly a 3D thing, but I am using adobe after effects) If I would know that the 13'' would run as good and without problems then I would save a lot of money. Oh yes, and mostly I edit HD material from Canon 5D Mark II camera. Please share your experience! Thanks, I.
