What is a good laptop for college and gaming?

I'm graduating this year (from high school) and parents want to get me a laptop for my grad gift. I'm wondering what is a great laptop for college/school related items but can also run main Steam games (tf2, dota 2, left 4 dead 2, etc.). Something that is also highly mobile. So something that has screen sizes of 13 - 15.
