I recently got not 1, but 2 MacBook Pros, 1 base unibody and a last model non-unibody(the "old" one was from my dad's work). I am still holding onto my PM G5 and I was wondering which machines I should use my copy of Photoshop CS4 on. My PM was recently upgraded with 8GB ram, for a total of 16GB, and a new 1.5 TB 7200RPM HDD. (check out my "hardware" section thing ) Should I upgrade the graphics card, if possible? I have a Quadro FX4500 already. P.S. My MBPs have the 9400M and 9600M GT (uni) and 8600M GT (non-uni).
