Which Mac Pro to buy for Logic Pro and Final Cut Pro X?

Hi, I'm considering to buy a Mac Pro for my personal studio. I have 2 choices in my mind: 1st one is the "Quad-core (one 3.2GHz Quad-Core Intel Xeon) with 6GB RAM", and the 2nd one is "12-core (Two 2.4GHz 6-Core Intel Xeon) with 12GB RAM". I'll be mainly using Logic Pro 9 and hardcore video editing in Final Cut Pro X. I know the fact that having higher GHz than more cores may benefit you at some point, and only those software applications that are well-written for using multiple cores will be able to utilize the power of 12-core. So, I need to know that are Logic and FCPX are such apps? Are they able to utilize the power of 12-cores or a Quad-core with more GHz will be better? I'm looking for fast operation and smoother workflow, and I'll also be using this computer for a very long time (so, its a major investment!).

So, the ultimate verdict is to whether to go for more clockspeed or more cores? Money is not the problem here, and I will add more RAMs, SSD according to the need later after couple of months, but considering nothing else I need you to compare between these two machines! If the 12-core machine is even 1% faster I'll go for it, but I don't want to end up spending more money on the machine with will have less power and utility.

Regards. 🙂
