I am a graphic designer, with my main workload consisting of producing a 150 page magazine each month, as well as occasional logo, web, identity work, etc. I spend most of my day in InDesign, with Photoshop and Illustrator thrown in. I currently use a 17" MBP 2.4 Ghz, 4 GB RAM hooked to a 23" ACD. The combo has served me well, but I am itching for more power, especially when working with the large documents in InDesign. I know I don't need all the power you video and photo guys need, but I would like to see more responsiveness when working. The base model mac pro is available in the Refurb store for $2399. Should I jump on this? Will I see any more responsiveness or other notable gains from jumping to the Mac Pro? I am debating pulling the trigger today for business tax purposes. Thanks!
