Nvidia 6600gt + dual monitors

I'm not much of a gamer and haven't played around with dual monitors too much. I do have an Ati 9600 and the dual monitor option is great as in I can drag my team speak program window to the other monitor. I just bought this Nvidia 6600 gt and I can't figure out how to enable this option correctly. I get the option of "clone" which does just that. I want to be able to run other programs on the other monitor. Can I do this with Nvidia?

 

Man!!!!!!!! I don't know why? I just went back into my device settings for about the 15th time since insatlling this card and now all of a sudden there is a new choice.. Dual View. Didn't see it before, but it is there now and is exactly what I wanted.
