Hi all!! I have an 8-Core 2.26Ghz Mac Pro 4,1. It is running: Samsung SSD 830 Apple HD5770 I am looking at upgrading the processors (for no particular reason other than boredom). I see a lot of people going from single quad to single hex but as I am running the 8 core I don't want to go down to one chip. So do you think the X5570 is a sensible choice? I can get a pair for under $400 so I think it makes more sense than a 5,1 flash and an X56** chip. Would love to hear from you all!! Thanks Future updates will be SATA III, USB III, and some more ram!!!
