Nvidia typically uses a proprietary driver and would have prompted you 
after install.  Your system may be using default settings (generic 
driver).  Go to:

    System --> Administration --> Hardware Drivers

if it shows active there you go; if not you can activate the driver 
there.  Once activated you should have:

    System --> Administration --> NVIDIA X Server Settings

to help control your card.

This is all based on my experience with my Nvidia card so hope it helps.
