As I am sure you know the new MacBooks were just released. I am wondering wether the 512 Mb will have a huge difference from the 1gb GDDR5 GPU memory? Also will the 2.3 quad core and the 2.6 quad have major differences. I plan on video editing, flash animation, photoshop, gaming , and various other things. My only concern is money and I was wondering if there would be any major differences.
