If this was for personal use I would without question go with a 2009 MP with hopes of upgrading later. I am trying to decide what to do from a business perspective. I have started a real estate photography business. I'm getting pretty busy right now. I currently work off of a borrowed Mac Pro 1,1 Quad 3.0 with 4 gigs of ram. This thing is sloooooooooow. I am also using LR5. I am looking to upgrade hardware to speed up my work flow. I have considered anything from a 2012 i5 mac mini to a 2009 4,1 Mac Pro with the hopes of upgrading later. My question is would it be prudent to consider a 2008 8 core Mac Pro with 32 gigs of ram for around $650 vs. buying a 2009 Mac Pro with hopes of upgrading soon? I need speed now. My goal is to get a 2009 model to upgrade, but I'm thinking at the rate I'm going I could be there pretty quickly. I just need to get that motor going faster than it is right now because time is money. The 2008's are going pretty cheap on eBay right now and some with maxed out ram. I use the HDRsoft merge to 32bit HDR plugin with Lightroom 5. It currently takes anywhere between 2 to 4 minutes to merge seven exposures. Will the 2008 MP reduce that time dramatically?
