Which would you buy? (Computer or laptop question)?

I've been wanting a new laptop/computer for a while now and have a computer and a laptop that I'm stuck with. I just can't choose which to buy. As I have a small bedroom, putting the computer in would be hard work, but it is rather good. I'm not sure If the laptop would come anyway near the computer? I'm wanting to use it for gaming, like Rome: Total War, Dragon Age: Origins and MMO's like LOTRO and Star Wars: Old Republic etc and obviously general internet uses, Facebook/Tumblr etc. At the moment I have a nice little Toshiba (Perfect for internet browsing and some games but it couldn't handle Dragon Age 2. I will still keep this laptop though.

Thank you for taking your time to answer this.|||Definitely the Alienware. Mainly because I've never heard of Advent and just looked it up and not getting good reviews. At least Alienware is a known company here in the states and are more gaming oriented. It also has a better graphics card.
