I have a 2008 Mac Pro that has been my trusty sidekick for seven years. It is finally starting to show its age and doing strange things, despite my upgrading to an SSD drive for the OS and all new memory. At this point I think it is time for me to consider upgrading to a newer model, but I'm unsure what to consider. I am not a professional anything. I use my system mainly to build websites, and the most powerful software that I use is Photoshop Elements. I often have multiple browsers open at the same time, all with multiple tabs open. I am pretty sure that I do not need a 12 core processor, and wonder if I even need 6 cores, that a 4 core processor might be just fine for my needs. What I mainly want to know is what model year (i.e. 2009 vs 2010 vs 2011), processor, and memory I should consider based on my usage. Thank you in advance for any input.
