Thanks pastrychef! I added your advice to Post #2.Reminder: Those who are using MacPro6,1, iMac15,1, or iMac17,1 system definition may need to re-apply the black screen fix.

It's best to wait an extra day to allow nvidia to update the web drivers.Update went smooth however as indicated at the top, Nvidia WebDrivers do not yet support 10.12.3 so they will STOP WORKING after the upgrade and you will lose graphics if using an Nvidia card. Hoping updates will be released soon.
Is this all they update in the web drivers anyways? Seems like nothing changes.Meanwhile you can set the NVDARequiredOS tag in the /S/L/E/NVDAStartupWeb.kext/Contents/Info.plist to 16D32. Reboot.
Works like a charm.
