I'm about a year into the Mac platform after switching from pc. My first Mac was a 17" MBP and I'm looking to get a Mac Pro. Like most I'm waiting to see when the new ones will come out. I have always been curious and just wanted to know can the processors be swapped out like on a pc? I realize this involves mother board issues and whatnot but the processors we're waiting for are the same ones that can be purchased by anyone. I always wondered why someone with say a 2008 Mac Pro could not just simply swap out the processors since the tower itself is still the same. Again, I'm fairly new but just was wondering if anyone knew the answer (s). Thanks again for any insight as I'm trying to really learn and understand the Mac system under the hood so to speak.
