I wanted to get some advice from the fine folks here at this here forum. For the next 18 months (hopefully) I'm going to be in charge of a large scale photography project for a client that will be sending me hundreds of 8- to 10-megapixel images a day for post processing, cataloging, organizing and filing. This is the config I plan on ordering, but adding another 250GB drive and 4GB of RAM: Dual 2.3GHz PowerPC G5 512MB DDR400 SDRAM (PC3200) - 2x256 250GB Serial ATA - 7200rpm ATI Radeon 9650 w/256MB DDR SDRAM Apple Cinema Display (20" flat panel) Apple Cinema Display (20" flat panel) AirPort Extreme Card 16x SuperDrive double-layer (DVD+R DL/DVD±RW/CD-RW) Bluetooth Module + Apple Wireless Keyboard & Mouse - U.S. English Mac OS X - U.S. English AppleCare Protection Plan for Power Mac (w/ or w/o Display) Here's what is important to me: I want to be able to open 30-40 images at a time very quickly in PhotoShop. I plan on putting 4 GB of Crucial Ram into this machine, so I assume that RAM is more a function of opening these images quickly than processor speed, correct? Or should I pay the extra 500.00 for the 2.7 (i.e. will that processor speed make that much of a difference in opening large lots of images). I want to run batch actions (filters, Fred Miranda actions, unsharp mask) with good speed. This, I know, is a processor function. My question is for the amount of images I will deal with on a daily basis, is 2.3 enough, or should I, again, look toward the 2.7? I'll be running Extensis Portfolio to a 1 terabyte Lacie external, I would assume that the 2.3 would run Portfolio fine. Last question - two 20" ACD's or one 23"? I need to have several images open and moving around - I assume I get more bang for my buck with the 20" ACD's. Thanks in advance.
