Depends on your needs. I would recommend a Macbook Pro. Its cool, light, stylish and well configured to run all the games If you want more power, look at a system such as Clevo D900c with user upgradable Gfx cards or Asus C90s with desktop processor which will blow away all other laptops for performance.
If you want a ultralight-ultraportable system, look at Lenovo X61. If you want a tough business class laptop, look at Lenovo T61 or Dell Latitude D830.
As you can see, it all depends on what are your needs from that laptop
