One of the big surprises at CES came when Nvidia announced it would be bringing G-Sync support to FreeSync monitors with an upcoming driver update for GeForce graphics card owners. Well, that driver (version 417.71 WHQL) is now available.

This is a big deal because there are far more FreeSync monitors than there are G-Sync ones. FreeSync displays also tend to be less expensive than similar G-Sync monitors. Part of the up-charge is to account for the G-Sync hardware, though Nvidia contests that G-Sync monitors undergo more stringent testing.
