Success on:
ASUS P8Z68-V PRO/GEN3
i7-2600K
Radeon HD 6850
8 GB Crucial 1333
SSD
New Install: Used UniBeast, MultiBeast, and Chameleon Wizard. No DSDT or SSDT.
I had a few issues to work through via trial and error, but below is the final setup (experienced folks may recognize I need more to, but everything appears to be working fine), but I'll leave as is unless issues come up. But it's running really smooth..... for now.
Booted fine after UniBeast install of Mavericks 10.9.5
