Silly Question About 3D

So I have my new Alienware 17 and not being too familiar with 3D on computers (and not really being too interested) I didn't specifically seek it out as a spec for my machine. I do have an option under my NVIDIA programs to Enable or Disable 3D Vision. Does that mean my machine is 3D capable? Haven't tried it yet because I guess I'm a little nervous about using something that may not be meant for my machine LOL!

Any ideas? Thank you!
If you have the 120 Hz screen then it would be 3d capable the internal graphic's will be disabled also. You most likely would have received the 3D bundle with it if purchased new. Thru the Dell Outlet you would need to contact support and request the bundle from them.
