What kind of laptop should I purchase?

I am planning on getting a new laptop without spending entirely too much (more than 600). I am not sure about how much space or what kind of processor I should have for what I want in a laptop. I want enough space for music (aprox. 3000 songs) and computer games. Each game is about 6 GB in hard drive and I have four of them. Also enough space for the basic Microsoft office and other typical programs. I'd appreciate any suggestions, even if it is out of my desired price range. Thanks ahead of time (:
