Here's the situation..I have $3000 to spend on a computer. I am a student so I can get the 2.3 for $2299 or the 2.7 for $2699. The question is: should I spend the extra $400 on the 2.7 or use that money to get a lot of RAM for the 2.3? I will mostly be using the computer for Logic 7 Pro and I need to get as much power as possible for my money. On the other hand I don't want to rebuy for at least a couple of years. Which should I get?
