There should be an option in your Display properties, settings tab. For your 2nd monitor, check "extend desktop onto this monitor". I have an X800XL, and that's what I did for mine. Also, I researched multitasking on nvidia cards and many ppl reported drastic slowdowns when you use 2 monitors at the same time. That's why I went w/ the ATI card. I had the 9800pro on dual displays and it worked great. Nvidia hasn't been good to me in the past, but who knows, it might just be me.
