what chart mine? maybe you cant read it right  there are no E5 2.7GHz Xeons on my chart
something else you are not taking into consideration i sell dual Xeons (mostly for video)
i make far more on a dual Xeon than a single system
yet here i am saying DONT WASTE YOUR MONEY.... 

2nd graph down

DUal 3.1GHz Xeon 16 cores is the fastest there is (blue)  these are E5
single 3.1 Xeon 8 core red  again E5  no  other Xeons
3930k @ 4.5GHz  green   i7 socket 2011

go down to 32 buffer..  enough said..

FYI ALL socket 2011 are the exact same silicon (processors)
the 3930k is the same as the 8 core with 2 cores turned off so they are the same.
stock 3930K runs @ 3.5 and turbos to 3.9GHz..

again a fool and his money.

Sorry, it's a 2.6, not 2.7.
But the logic still holds true.
 
E5 or E-5?
That makes a difference and would be the explanation in the chart comparison where the faster speed is the slower processor.

That still makes it the only chip relative in that chart.
And it still apperas as if the i7 is overclocked?

2nd chart down ONLY
 not the 3rd one  the 2nd is done with a newer test vs the older test..
too hard to explain the issues
  beside look again @ 32buffer if you really wanted to use that chart..  3930k/60X is still winning over the 8 core 2.6GHz
 

Only the third chart is relative to my configurations.

Bottom line, it works, it works good, and has been better than the other chips I've used.

Is there anyway to get you back to the OP because your point is moot and doesn't focus on my considerations.

Stipes, Scott knows what he is talking about as he builds professional DAWs for a living.

To answer your question: Which of those two chips would I buy, for my uses?  Answer: neither.  For sample streaming, the speed of both of them are too slow to be cost effective.  FWIW, the key developer/tester of MIR at Vienna Symphonic Libraries uses a 3930k, and that does quite well enough for him.

Beyond the obvious, the answer to your question is actually a question: What do you intend to do with the system? 

What you will need will vary depending on how many tracks you intend to record, if you are doing live recording.  In that case your interface matters a great deal.  If you are going do be doing heavy sample streaming, generally, a faster CPU will be needed.  Sample streaming = faster speeds; effects processing = more cores.

Anyway, if you want to buy one of those xeons, go ahead.  After all, it is your money.  It is just that for audio purposes, there are better options for much less money, except in rare situations.

Thanks for a rational and reasonable response.
Excuses aside, I would not buy anything from ADK after that.
And I'm sure they build good computers.

I did notice they sell the same configuration as a professional grade on their site though.

After seeking out an impartial benchmark test that runs them in normal values, it appears as the 2.0 ghz is actually the better chip here.

Bear in mind, I'm streaming samples with this one and having no problem doing so. Although I've changed my thinking in what I run drastically. Trying to keep as minimal as possible. And I've honestly dumped the whole idea of everything in the box and have a happier medium in hybrid systeming.
However, I decided to try different and use a dual socket MB. I was using multiple laptops/netbooks/desktops synced but not networked, because they were 'adequate' at one time or abandoned by customers that didn't want to pay for the parts after I fixed it for them. And I almost always have to fix what some expert did for them. I also have a couple that were given to me.
I feel this MB gives me another 2-3 years on my usual timeline of usage while allowing me to upgrade as I go. I seriously was considering the Rain Computers before I decided to go this route. Even researched Music Computing while gathering the pros and cons. Read good things in many places about Studiocat but my thinking had already shifted by then.

After reading a true benchmark of these processors elsewhere though, I may step up to one of the eight core instead of two four  or six core.

Hey Stipes, don't take Scott's sunny demeanor too seriously, he really does mean well and was trying to give you helpful and informed advice even if it didn't come across that way (with the added bonus of typos from banging his noggin on his keyboard).

Anyway, the ground upon which your original query trods was already well tilled by Scott and Vin a while back elsewhere:

Ahh dang Goddard you see right thru my gruff exterior
you are going to ruin my rep as a grumpy old man..

Oh, I'm sure we can disagree on something Scott.

So, what's better, Skyline or Empress or Gold Star or...?

  Empress for chilli spaghetti, skyline for burrito, coney is any of them
i cant eat there as often as i would like anymore sadly.. i have to have mass dose of hot sauce
and my tummy is getting to not like it anymore. i hate getting old.. you just gave away your location FYI

only people from this area evn know of them.. however my first introduction to chili spaghetti was actually in Ft Myers FL.
my wife is from here and she made me go. imagine trying to tell an Italian that chili and spaghetti go together i of course said what a
stupid idea  my wife was actually right for a change
