What Mac do you guys use to Post process your photos? I've found that while it's acceptable, the general performance of my mac book pro hasn't been satisfactory, especially for raw files. I primarily use CS3 and Nikon Capture NX. I do plan to begin using Aperture 2 once I get my hands on it, but considering a hardware upgrade before that. I figured that desktops are always faster than laptops in numerous ways... would a move to a 2.4ghz iMac or mac pro be a very significant increase in workflow speed? Would it be worth the money? Thank you very much, and best regards.
