Howdy, Well as a breif introduction i am new here as well as new to mac's. i just made the big conversion from pc to mc (thank god). I recently purchased a new mac pro (4 core) and new mac book pro. More recently I learned that apple is releasing an 8-core mac pro. This fustrates me a little because I JUST purchased the 4 core. Now I am a design student and trust me this mac pro definately meets my needs, but I am wondering how big of a difference the 8 core makes? Would it be worth returning or selling my mac pro and getting the 8 core?
