Hey everyone. An interesting circumstance: Two weeks ago Apple replaced my first gen MBP with a new one for free (under AppleCare) due to some ongoing issues. After loving this laptop, I soon realized that, after looking at my receipt, I could essentially change this laptop out for the 2nd tier MBP for only $500 ($200 restocking + $300 student price difference). Now, to note, I am a visual effects student and could benefit from the added features. I know the processor speed upgrade is minimal, but aside from that and the extra GPU memory, I can upgrade everything else myself. What do you all think? Is the extra CPU, memory, HDD space and GPU memory worth $500, especially considering I got this one for free?
