Heres what I did so far in order:

(1) updated to 280.19 nvidia driver
(2) I swapped out the nv_disp.inf file with the one linked
(3) Used Invidia Inspector to change
(a) SLI compatibility bits (DX10): 0x000000F5
(b) NVIDIA predefined SLI mode on DirectX 10: SLI_PREREFINED_MODE_DX10_FORCE_AFR

I hope changing the nv_disp.inf was correct. Wasn't sure if that was necessary with this beta driver also. Please let me know if you see anything wrong or if I can tweak something. I'll repost if I have any better results

Thanks again for getting this working for me

Once you've installed the driver, changing the nv_disp.inf file doesn't do anything. It's only referenced during the driver install. As the 280.19 driver is a unified GeForce driver, your card is supported. However, nv_dips.inf files are specific to driver version. So if you try to reinstall the driver from the C:\nvidia folder by running the setup.exe it will likely fail because the driver version in the nv_disp.inf file header is wrong. You can read the .inf files with notepad.
