What the 'experts' mean is that they can cram more hard drives and other stuff INSIDE it, and you can't argue with that.

Nearly everything apart from the video cards (they're a custom job) is replaceable in the current Mac Pro - including the processor. The video card significantly influences how well Premiere, Final Cut and After Effects works.

The only thing I can not say much about is the Radeon R9 280x video card. The other programs will work fine with 6-core but if you want fast - 12-core will give it. You can settle for the 6-core but if you are doing any heavy work with After Effects you will really appreciate the 12-core. I can encode a two hour video in about ten minutes. i also keep an original Nvidia GT120 video card in it incase I need to access the boot screen but I don't keep a monitor attached to it.ДЄs to your question - will you use 12 cores - yes! Your video card GPU and your system CPU's will work together to encode videos, provide you with real-time playback while editing, and smooth timeline scrubbing. I have two-six cores giving me 12 cores, 32 GB of memory (would love more ) a 512GB SSD main drive from OWC and the video card is a Nvidia GeForce GTX780. I have a 2009 Mac Pro that has had it's firmware flashed so it operates as a 2010 - 5.1 so I could use Westmere processors. I work with all the Adobe products you have listed above and have dabbled with Final Cut Pro X.
