External monitor for MacBook Pro

Hi everyone,

My friend just gave me a Dell SP2008WFP Flat Panel Monitor, and I would like to use it as an extended monitor for my Macbook Pro. What cord would I need to buy from Apple to use the monitor, along with my Macbook monitor?

I was looking on the Apple website, and I'm confused if its the:

Mini DisplayPort to VGA Adapter
Apple Mini-DVI to Video Adapter
Apple Mini-DVI to DVI Adapter

or am I in the wrong ballpark and its something completely different?

Thanks for any help provided

PS. I also have all the cables that came with the monitor (White DVI cable/Blue DVI Cable, USB Cable and Power Cable)
