Hi, I need help on the best configuration of a new mac pro. My main work is large, hi-res Photoshop files with many layers. I also do 3D work in Modo but this is only on still images rendered out at large file sizes - no animation work. Apart from this the machine would also be used for iTunes, email, safari -the usual stuff. So I am looking at the best configuration for those requirements. I am currently looking at these two options: Apple Mac Pro 6 Core 3.33GHz costing about £1,999.00 or Apple Mac Pro 12 Core 2.66GHz costing about £3,349.00. In both options I would install 32GB RAM. So, does the extra cores in the 12 core model really justify the huge price increase for my type of work? My concern is that the cost increase simply wont be justified against the actual performance improvements? Any advice on this would be greatly appreciated. A further detail which might make a difference: I currently have an 8 core Mac Pro (late 2008 model). In theory I could utilise the cores in this machine to perform network renders in modo thus benefitting from 14 cores worth of render processing. I'm not sure how efficient modo network rendering is but at least theoretically this seems like a good option to me. But again, advice from anyone with this more figured out would be appreciated. Many thanks.
