I have been running an early 2008 3,1 Mac Pro 8 Core 2.8Ghz machine. It has 32 Gig of RAM, Apple Hardware RAID card, OWC Mercury Accelsior 480Gig SSD (this is an amazing card), 4 WD Red Caviar Hard Drives in RAID 0+1 for image storage. The machine is used for photography exclusively - processing images in Lightroom and working multiple layered images in Photoshop. Its been an excellent machine all around. I was planning to update it to the new 2013 Mac Pro - but I am honestly disappointed in this machine. It really seems to me to optimised for 4K video editing - which I just don't need. Also the price of entry is very steep for even a 6-core machine - let alone an 8 core with 64 Gig RAM and 1TB flash. With an external TH2 chassis its going to run close to 10k AUD - ouch. I have an opportunity to get a 2010 Mac Pro 5,1 at a pretty good price. Its an 8-Core machine 2.4 Ghz and it comes with the APPLE RAID card. I could put 64 Gig of RAM in it as well as my OWC Mercury Accelsior which would give me a pretty nice speed bump upgrade as well as a nice future path for processor upgrade. Plus this machine can go to 128 Gig RAM in the future - overkill for now, but nice to know. Worth upgrading the video card in the 2010? Thoughts on wether this might be a worthwhile upgrade?
