Which driver to install for a GeForce GT 520MX graphics card?

I have the following drivers shown on my "Additional drivers" list. I am confused as to which one is stable and usable that doesn't break my system. I use Steam for games. I would like to test few of the games available there.

Solution 1:

A search for the NVIDIA driver for the GeForce GT 520MX graphics card at the NVIDIA Driver Downloads webpage returned the following result:

Based on the result from NVIDIA Driver Downloads, the recommended graphics driver to install for your graphics card is nvidia-331 proprietary tested graphics driver. After you have installed nvidia-331 using the Additional Drivers utility and rebooted the computer, you can check your installation in the Additional Drivers utility . There should be a line underneath the graphics card model name that says: This device is using the recommended driver.
