It's even mo-bettah than that: once installed, Mint will ask you if you want to install the closed-source Nvidia driver on first boot.
You can, of course, always download the Nvidia drivers from Nvidia and install them yourself, however note that if you take this approach, when the kernel gets upgraded via the update manager (a little program that essentially takes the place of all of those annoying Windows apps that always check to see if there's a new version of the software; however it does it for any software installed through the package manager), you will need to manually re-build the Nvidia drivers since it doesn't happen automagically anymore
