I run the above machine and have had a good experience with it since purchasing it new about 8 years ago. Unfortunately I have come to the realization that support for my browsers, mainly Firefox is coming to an end and I am already having issues with it. I use the MacPro for desktop publishing, mainly Adobe CS4 Photoshop and Indesign which runs great with no issues. It seems absurd that I would have to consider basically scrapping my trusty mac for the sake of upgrading to a new mac just so I can run the current browsers. It currently runs Snow Leopard which I have heard from reliable sources, is the most robust version of the Mac OS for this generation of macs. Anyone in a similar situation? I really want to avoid upgrading my hardware as I am a miserly old-school graphics guy.
