Try adding USBBusFix=Yes to your flags.
Also ensure that you disable VT- options in bios.
With regards to the SAS ports... The likelihood of getting those working in OS X are slim at best.
Article: OS X 10.9.2 Update
Update works straight from MAC App Store on Gigabyte X79S-UP5-Wifi - i7 3820. Only needed to patch sound and TRIM. Bluetooth doesn't work, but then again it never did. So looks to be Good to go :headbang: :clap:

I may say Impressive rig you have there.
Running a Hackintosh ain't for the faint of heart, it comes bundled with lots of stress and less hair.
I see you attempting to install OS X Lion... You are better off trying to run OS X Mountain Lion or Mavericks on this machine. I think...
Regarding your sound, have you tried multibeast?
* I use Realtek with DSDT edit for ALC898, It is up to you, whether you want to use the DSDT or Non-DSDT version.
* Also as noted to me on the previous pages, you need to use npci=0x2000 instead of npci=0x3000.
Regarding your system working slow...
I am not sure about the NV*** kext since i don't have a GTX7xx to test it on, but try the following flags:
-v cpus=1 npci=0x2000 GraphicsEnabler=yes/no USBBusFix=Yes
Ensure that you enable XHCI and EHCI in bios.
*I am not sure if the gtx7xx needs the GE to be yes or no.
When you manually type in the command, boot works. What commands do you use?
Which version of multibeast you using?
What is your configuration setup you use in multibeast?
About the DSDT, I don't think you need one, although i use one mainly for sound.
I actually don't use sleep on my system. I could test it and get back to you?
If I am correct, the GTS 250 should work natively without any customisations, and sleep should work. I'll test mine, in that case.
I just tested sleep. It would seem that the system does go into sleep mode...
