I am about to buy my first macbook pro and I know very little about computers in general. I am buying a 13" macbook pro. I know I want an SSD. It will be 4GB RAM. I am not a big gamer, but I do play The Sims. I keep a decent amount of music and pictures on my computer, but I don't do a lot of editing. I will mostly be using my computer for email and work. However, I do plan to download music and watch some movies, and play The Sims occasionally. What I am trying to decide is this: 1. Should I get the 2.4GHz dual-core i5 or the 2.8-core i7 ($200 difference)? 2. Should I get the 128GB or the 256GB SSD Hard Drive ($400 difference)? Thanks for your help!
