Ivy Bridge-E and 10.9 questions

[DJenkins]

Hi guys I'm about to start my second build and just wanted to wrap up a few questions I have floating around in my head. A few of these are aimed at RampageDev but I thought I'd post up here so others could get use from the responses.

Build is as follows:
X79 Asus Rampage IV Formula
i7 4930K
Corsair H80i Cooler
32GB G.Skill Ripjaws Z (4 x 8GB)
EVGA GTX780 Classified

I'll also be repurposing a few bits from my current machine (see sig).

To clarify why I'm asking, I have seen a few builds with the RIVF AND RIVE but most are using Sandy Bridge-E rather than IB-E.

Power management:
Has Mavericks 10.9 enabled complete native power management on IB-E processors? E.g. Turbo, speed step, sleep etc. I did see some announcement that 2011 power management was working under 10.9 but I can't find anyone sharing info in their build threads.

Installation:
For my current 12 core build I created the installation onto a target drive from a 'real' mac pro. I then added the DSDT, kexts etc. from there and swapped it over into my mackintosh and everything was pretty much sorted. All I had to do was swap over a modified mach kernel.

Is there any reason why I shouldn't use this method again with Mavericks?
I know rampagedev has instructions on his site for myHackwhich I can follow otherwise.

DSDT:
Also this one is for RampageDev - I saw an update saying you are now using SSDT to inject values into DSDT or something along those lines. Is the RIVF .dmg download on your site using this new method, and are the 'How To Install DSDT' instructions up to date with this?

Am I correct in saying that I should only perform your DSDT instructions after 10.9 installation and once successfully booted into the X79 system - not just unpack and add the files to their locations while the HDD is attached to my 'real' mac as an external drive?

Thanks for any help!
