I am going to be getting a new PB 15 today. I am trying to deciede whether or not to go with the top of the line from last version PB refurb up on the special deals or get a new PB. I have the money to buy either one. I am concerned that the old ones might not be a good as the new ones for video/audio editing and gaming. Which should I get? Should I save money on the computer and get the Garage band Jam pack, or get the newest version?
