Greetings, My father bought a 2006 Mac pro tower. Its has the Intel Xeon 2.66 dual core cpu and is running Mac OSX Lion, 10.7.5. Here are all the specs: http://www.everymac.com/systems/apple/mac_pro/specs/mac-pro-quad-2.66-specs.html He want to be able to run 64bit software and the latest version of bootcamp that supports Windows 10. Is it possible for him to upgrade enough for that? Can the components be upgraded inside the machine, such as logic board, in order to accommodate it if necessary? Should he buy a newer Mac Tower or just get an Imac. Our budget is $500 - $1000. I appreciate the help! Thanks!
