hi guys i ordered the new macbook pro 15inch i5 2.53 and am planning on doing photo editing using aperture and vid editing via final cut pro, i am going to school for film sooon, so after ordering I noticed that the i7 was not a significant amount more expensive and regret not ordering that one, unless it is not needed but i want this machine to work well for all types of projects and if i7 is significantly better for my needs i will cancel the order and buy a i7, any help on this matter is appriciated
