I will soon be purchasing the new macbook pro to edit AVID on. I will be upgrading the RAM, and I am hoping I will be good with 512 since I will be putting all my video on an external. But why spend $270 on upgrading the processor for such a SMALL bump? Am I mistaken, and it isn't a small bump? Will the extra cache help me do something on the 2.7, that wont let me do it on the 2.6? From what I have read, it will help increase render speed by 8-12 seconds. I know it can add up, but really??...I also understand, "hey already spending over 3k, why not just juice it all" But with the applecare also being added to the price...its really building up. So...why upgrade to the 2.7, and just use that money towards something you will really get use out of. Like putting it towards applecare or thunderbolt external?
