Hi, I have a 2012 quad core mac pro. I was wondering whether a 6 core w3680 can be used to upgrade it. Also, what can be done to improve the performance of the current set up. its a quad xeon 3.2 ghz with 6 gb of ram and ati 5770 gpu. working with photoshop file as large as 820 mb cripples the system. I also get large page out files, does that mean I need more ram? Guess i've asked a lot of questions and thanks in advance.
