I'm a photographer processing large batches of digital images (weddings). My specific need is a computer optimized for running Adobe Lightroom, Photoshop CS3 with Nik and OnOne plugins concurrently with STABILITY and speed. Currently using 2 year old system: Win XP Pro 32 bit with AMD x2 4400 CPU, 4GB ram. System works acceptably if I don't try to run all concurrently. When heavily multitasking, system bogs down, often hangs, and too frequently CS3 will crash (usually when running OnOne Phototools). I've compared speed of my system (2281) with current Macs using Geekbench and see a potential 3 to 4X improvement with the stock MacPro 8 core. Mac users commenting on my favorite photography forums all speak to the smooth, reliable multitasking of the Macs, even when using Mac laptops. I'm looking at the standard configuration mac pro (8 cores 2.8, 2GB Ram, ATI video, 320 GB HD) plus adding additional RAM and larger drives. I am comfortable with performing hardware upgrades myself. My plan now is to add 8 GB RAM and two 1TB drives to the stock configuration. I currently run two monitors: Dell 24" (1920x1200) and 19" (1280x1024) which I plan to keep. My questions: For my purposes, is there a compelling reason to upgrade the video card from the stock ATI? (I'm not a gamer.) Any problems with the dual monitors noted above? Can the stock system drive be easily cloned to a larger 1 TB drive without third party software? Would it be better to buy the system with the single 1 TB drive option rather than doing an upgrade myself? I understand RAM must be upgraded in pairs. Is there any reason not to use the stock 2 GB RAM and add 8 GB (4 x 2 GB) for a total of 10 GB? (Looking at OWC RAM) Is there an optimum RAM configuration for my uses? The software I must use with my photo lab for uploading final images for print and for album layout and production is currently Windows only. Would you recommend keeping the current PC just for running that software, or would you recommend installing Windows in a virtual machine on the Mac for convenience? Any other comments which would help me select a more efficient and reliable system for image post-processing is appreciated.
