I need to buy a new desktop late summer (end of July 2011) for a new academic job I'm starting, and it would be great to get some advice. I have a budget of about $4500-$5000 from the school. Currently, I have a Mac Pro 1,1 Quad 2x2.66 at home, and it has served me well throughout graduate school, and I was originally thinking of purchasing the 3.2 Quad Mac Pro as my new office computer. But now I'm having second thoughts and thinking of possibly upgrading my original mac pro as well with the budget. What do you guys think of these two options. Option 1: Buy 3.2 Quad Mac Pro for office, live with my Mac Pro 1,1 quad at home Option 2: Buy two 27 inch iMac Quad update (assuming that happens in June/July) with Sandybridge and Thunderbolt. My needs: - Office: A fast computer for regular office work and statistical estimation/computation that can take advantage of multi-threading - Home: Statistical estimation/computer PLUS Adobe Photoshop RAW image processing/editing, some short HD home movie editing - I do not need more than two harddrives, 16gb of memory are probably enough for my needs Do you think that I would experience a lot of performance or speed bump from the 3.2 quad Mac Pro above the new iMac that would justify the extra cost? Thanks.
