Casa Nova

So I'm looking to get a new laptop soon and I'm not quite sure what I want. Basically I need it to be able to handle tons of large applications open at once like photoshop, Reason etc. I want to do my graphics stuff on it, aswell as my music production & handle my normal business type stuff. I heard the macs are the greatest for this, but I dunno, Im just not really that into them. So I'm looking at either getting a macbook, Dell XPS, or a Ferrari 3000. What do you use, and recommend?
