I'm not quite sure about the difference but all I know is that the drivers from
Asus support is rarely updated but they are optimized to work better on the notebook.
If you download the drivers from
nVidia then you can get the latest drivers they have released, try new beta drivers, and get back to old drivers if they worked better.
You can stumble on issues on the way when you are updating your GPU drivers, so the best way when you install new drivers then choose custom install, and check for "clean install", then install.
