Thanks Tony and everyone who commented on this, my X58-UD3R is up to speed now after Googling and reading stuff. Here was my experience...
Did Update First Time, Instead Of Combo:
Panicked and reformatted my Mac, but had a SuperDuper clone I could restore files with... so proceeded to Combo update and use:
MultiBeast which worked but couldn't boot from HDD using UserDSDT option only:
Had to install RC4 1.1.9 on top, that got it working... using DType theme yo!
Didn't realize I had to rollback USB's either:
I cheated booted my Windows on 2nd HDD and installed kexts from there (MacDrive 8) had to -f -x boot I think...
Had no Audio when I stopped using iBoot cd:
Figured out the LegacyHDA I needed and rolled back AppleHDA too.
Sorry for the horrible write up,
