I'm finally selling my 2007 Mac Pro 2.66 to make room for a new tower. I noticed how much my current Mac Pro was showing its age when my new iMac 27" with i7 easily kicked its ass! So now I'm looking for a recommendation for a new Mac Pro. I'm a full time working photographer who shoots with Canon 1Ds III, and 5D MK II's. Both camera are 21MP and produce large RAW files that tax the computer once adding layers and actions. My main use of softwares are Photoshop CS5, and Aperture 3, and Photo mechanic. I'm not into gaming, video, or 3d. Looking for a great value that will be a good match to my new Apple 27" LED display. Thanks!!!
