Guys, they issued a driver this morning
http://nvidia.custhelp.com/app/answers/detail/a_id/3738
They said to do a custom/clean install.
"Hi Kyle,
We just released a new hotfix driver that should help with the BF4 DX error in SLI mode. If you haven't already updated then please give this new driver a try and see if that helps. You can download the new driver here: http://nvidia.custhelp.com/app/answers/detail/a_id/3738. When installing the new driver please select the "Custom (Advanced)" install option and then put a checkmark in the "Perform clean install" option. This will help insure a clean install.
Best regards,
Ray"
