Hello... I am planning to purchase a new apple laptop and needed some help choosing which one. I know that I am going into engineering (computer/electricial), but I also am going to play a lot of games on my Window's partition. I would be playing games found on PS2/PS3/and XBox. I wanted to choose between these models: 1) The Black Macbook 2) The base line 15" MBP 3) the best 15" MBP Thanks for any suggestions.
