Best Practical CPU's for Chess Analysis

I have done alot of research on different CPU's and I am considering purchasing either a Laptop or Desktop for personal use. But would also like this to be a complete monster in chess analysis. After countless hours of research I have discovered that the best "Practically Priced" Laptop CPU is the i7-4900MQ and the best "Practical Priced" Desktop CPU is the i7-4930K. What I mean by practical is cost and performance.

I have found someone who has an i7-4900MQ and had them load Arena 3.0 and Houdini 1.5a and see how many Kn/s they got on the starting postion. The result was about 6,700 kn/s in the first 3 seconds.

My Question is...

Does anyone out there have a i7-4930K processor on their computer?

How many Kn/s does it get off of the starting postion in the first 3 seconds with the Houdini 1.5a engine in Arena?

What are your thoughts on my two selections, Have I overlooked something?

CPU clock speed and number of cores make a difference.  Also the engine you use will vary the speed depending on how it is written.  I think you're chasing the Holy Grail and no matter how much research you do, there are so many variables that you won't find a single "best" solution.

What you are looking at is the starting position.  Are you aware that these engines use opening book databases and that the database being used, its size and format will have an effect.  There is little or no "analysis" being done at the opening position.

Which flavor of linux do you favor?

I favor chocolate linux

@pfren is right, although multiple cores (not hyperthreaded virtual cores) do increase either the speed or depth of the analysis depending on your settings if your engine is capable of using them.

It really depends on what you want the computer for.  If you expect to win online computer vs. computer battles, you'd better become a programmer.  If you expect a powerful engine to take you to the very top of analytical nirvana, then you're wasting your time because humans are not capable of playing and seeing 30 plies into a combination in OTB play and any of the current batch of engines are better than you (we) will ever be.  And if you expect to be able to use it to "cheat" in online play, forget it because you won't be online here very long.

Holy mother of you're doing it wrong.
