In what part of this workflow will Mac Pro actully save us a lot of time?

Question

Although the nMP is really tempting, I'm starting to get second thoughts in terms of how much time it will actually save us......
In our studio, we do a daily, 30 min. 3 camera technews show in 1080p for YouTube.
Until now, we've been using a 2010 MacPro 8 core 2.4ghz and a MacBook Pro i7 2013.
In our workflow, we record the show in less than an hour. Importing/transcoding is roughly 30 minutes. Multicam editing takes 2-3 hours in Final Cut Pro X. Exporting / encoding takes around 30 minutes. Upload it yet again around 30 minutes.
While waiting for the 6 core nMP D500 we ordered in January, the numbers I see, are starting to worry me.
It seems that the real difference in day-to-day work on the nMP is considerably less that we expected. It's hard to put numbers on expectations, but we were assuming that the nMP with dual GPU would be more than twice as fast as our existing exporting on the old MP and MbP.
The numbers we see in speed tests seems to be all like a few seconds faster here and there likewww.barefeats.com/tube05.html shows us. For us, it doesn't mean much if an export takes 2-4 minutes more or less - it takes longer to go for the toilet or a cup of coffee anyway.
To me it seems that the parts of our workflow, where we can shave of time, is transcoding and encoding. The editing takes the time it takes anyway.
So I'm getting a bit nervous that the investment is not worth it compared to the machines we already have.
I'd really like to hear from you guys that actually tried the nMP - is it all about 14 seconds faster here end 57 seconds faster there or am I missing / misinterpreting the numbers in stuff like Barefeat.com ?
Note: it almost seems to me that faster storage (like a Pegasus) for our existing tools, would give us the same speed boost as the nMP in itself???
Note 2: it almost seems that putting a 7970 gpu (or two) in our MacPro tower instead of the Quadro 4000 we use now, will give the same speedbump as the nMP in itself???

Answer 1

I have the new Mac Pro black cylinder (fully maxxed out) wiht a Pegasus2 R6 array atached ot it via the thunderbolt 2 port.  I also have an early 2008 Mac Pro 8-core machine that until recently I used for video editing in both FCP X and Adobe Premeire Pro CC as well as a high end mid-2012 Macbook Pro with Retina Display..  On the 2008 Mac Pro I used a two disk array in raid 0 for high speed access to video files.  My 2008 Mac Pro was outfitted a couple of years ago with an nVidia GTX285 graphics card and the old system is in good shape and is still being used for some tasks. On the 2012 Macbook Pro with Retina Display I have a six TB raid 0 array. 
My experience with the new Mac Pro has been that for any software that makes good use of multiple cores and the powerful Open CL architecture of the AMD W700 graphics cards in the new Mac Pro, this machine is much much faster than my older Mac Pro  A thorough review of the New Mac Pro with many benchmarks in the latest issue of Mac World bears this out with specific numbers comparing the new Mac Pro to the latest Macbook Pro with Retina Display and the latest high end iMac.  In every case the new Mac Pro was significantly faster than those machines for multiple core or graphics intensive tasks.  I have no regrets about purchasing the new Mac Pro and in fact, I love it!
However, the new Mac Pro is designed to excel at specific tasks, e.g., 4K video editing, 3D modeling and animation, editing very large photo files, and motion graphics such as Motion 5.  To fully realize the speed of the new Mac Pro it must be paired with a suitable high speed raid array.  If you do those kinds of activities and if you have the resources to purchase a high speed disk array like the Pegasus2, then you will see that the new Mac Pro is in a league of its own.
