I have a few quick questions. I am going to be buying 1 of these two machines tonight and I have been contemplating which to go with for nearly two weeks. I have been editing on a core 2 duo 2.2 Ghz mbp for 2 years now and I have been desperately waiting for the 2010 mac pro refresh. I plan on using them for editing hd video in final cut / premiere, after effects, photoshop, lightroom and some gaming. The cost difference before a 3rd party ram upgrade boils down to roughly $3800 for 6 core vs $5000 for the 12 core (i have the education discount as I work for a university). I also don't earn my living through these computers as of yet, but I have done more than a handful of freelance work over the last year outside of my fulltime job, as well as having recently finished a feature length film. (shameless plug of trailer can be found here: http://www.youtube.com/watch?v=X5Yg1I6h4lI) Ok, having said all that, and understanding that neither 3800 or 5000 is an insignificant amount of money, I have a few questions on which investment makes the most sense for me. For starters, what is the turbo boosted speed of each of the two chips i am looking at, and how many cores can be turbo boosted on each. I haven't quite been able to figure that out yet on my own. Secondly, I realize that only AE will really take advantage of 12 cores at this stage (although final cut may get an update soon enough that changes all of this) but what sort of performance difference should I expect if both systems have roughly the same amount of ram? I have read a bit on this on macperformanceguide.com but he doesnt spend a great deal of analysis on after effects or programs that may actually tax the entire system. Mostly though, for this sort of purchase I just want overall opinions and advice, heh. Any thoughts are very welcome before I finally pull the trigger on one of these systems, and thanks in advance for any help.
