I'd probably pick Alienware, but I'm really going to encourage you to look into building your own more. It's such a cost cutter, particularly when you're talking about spending $3k on a system that you want to last for a while. $3k worth of parts on Newegg will get you a LOT more than $3k worth of Alienware or Dell XPS.
