Current setup: MP 2007 3GHz Dual Cuad-Core, 9 GB RAM, 30" ACD I use my Mac Pro for making large magazines and books, and recently I got my largest project ever which will be over 1000 pages. Since the current MP is getting older and I'm starting to notice lagging when working in InDesign CS4, I was thinking of upgrading to the top-of-the-line 12-core 2.93GHz with 16GB RAM. Now, I have been pondering this question over and over. Is it too early? Will I see a speed increase which would make the investment reasonable? Or should I just stick to my current setup? I got his result when running it through Geekbench: Any thoughts would be highly appreciated!
