I am going to be saving up for buying my first MBP I use quite a lot of applications for photo editing, graphic designing, video editing, and composing music. I also like to play games. I think I'd be best with the 2.5GHz, with the 4GB ram. I am unsure though of other things to get, or if this is the right choice. I am hoping to save up by around March, or May. Any ideas?
