I suggest that you do a google search for "Mactracker", download it, and compare all the information that this free program will make available to you. The Mactracker database has all the specification information for each Mac made and you can even determine what upgrades can be done to the model you now own. The database is regularly updated so you will be getting the latest information when you download it. I use Mactracker constantly in my volunteer work because it is much easier to refer to it than to try to memorize all the specs for dozens of Macs.
