Nvidia GPU. Gsync or Freesync monitor? Why?

[Mr_Sukebe]

Hoping that someone here can enlighten me.

As I understand it Nvidia GPUs are now capable of interfacing with Freesync monitors.

Freesync monitors seem to be substantially cheaper, so what benefit do you get from paying for a Gsync unit?

Thanks. Had a scan at the freesync compatible, and they're not THAT much cheaper than Gsync.
Guess I need to save up for a good Gsync unit.
