Laptop with two video cards....?

I recently purchased a Satellite A665. I got it so I could game on the go. It has two video cards though, a built in Intel and a dedicated NVIDIA Card. When games load their using the Intel card and not the NVIDIA card. How do I get it to load the NVIDIA card?|||go into the game config and it will have a option like what resolution and details and they should be a graphics display drop down box and pick the NVIDIA card



and you have one video card the NVIDIA



the Intel is a chip set what's integrated into the mother board
