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.
Looking at the hardware requirments for A2, I'd say you'll be disappointed with anything but a Mac Pro (others however, might be fine with your MBP & A2).
Your sig line doesn't specify OS version.
2GB is clearly not much if running Leopard & anything else, deficient for sure w/A2.
Your older C2D MBP will recognize up to 3GB RAM, RAM for your MBP is not that expensive...recommend you max the RAM. 2.16Ghz MBP shipped with single 1GB module installed, 1 empty slot. That alone
may make a significant difference, being constrained as you are with limited RAM.
Next, since we can't tell from your description what you feel is lacking in the workflow speed, I'll assume you have either the original 120GB 5.4k rpm HD installed? Or worse the 200GB 4.2k optional HD?
It's more money, but you might get significantly faster performance in load/save times for RAW images (seeing your sig again, and assuming you are capturing/using NX for that purpose w/D300) if you upgrade the HD to a
7.2k rpm Hitachi 7k200 200GB drive, which is now down to $170 from newegg or zoomfly.
Try those two things, and if you still don't like the performance of the MBP, before upgrading to a MP, if you can wait until early summer (May for Intel) when Apple should have released the Monteviña MBP's, which promises slightly more speed from a faster front side bus memory system, slightly faster CPU as compared to what you have now, and either longer battery life from the CPU which will use less power than current Penryn models to be announced any day now, or higher performing GPU's that should be in those models by summer. Look for 2nd gen., better LED bl screens too. All good stuff coming to the MBP's if you can wait

.
Still won't have as much performance as MP, but will likely outclass any iMac on sale currently.
