Hello folks, I'm looking to buy a new macbook as my current one can't handle HD footage (it's old!) I'm looking at the top of the range 15in model, but I don't know if I need all of those specs. Do I need quad core, or the NVIDIA GeForce GT 750M graphics card. I may also prefer a 13in model for reduced weight as I'm travelling a lot. I borrowed a friends macbook pro to do a project and it handled it fine. She can't remember the specs but it's 13in so must be duo core and minus a fancy graphics card. I'd like to 'future proof' my purchase but I'm pretty skint so don't want to spend money for the sake of it! I'll be using Premiere, After Effects and Flash. Your help is much appreciated!
