Ok, let's try these:
1. Essential system
2. ALC888 by Taruga (not sure about this since I use usb audio)
3. ICHx Fixed
4. Use vanilla kernel so no choices there.
5. Realtek R1000
6. Openhaltrestart and some bios from AppleSMBIOS submenu
7. No choices there
8. You have such a new graphics card that I don't know if any of these work, try choosing NVInject that matches with memory on graphics card.
9. No need to select anything there.

Good luck
