Noob need laptop help, want a good laptop fore gaming

As i have written above.

I am curently looking att Sony´s Vivo series and the Dell XPS M170.

I´m going to college soon in the summer, and both of the computer brands fill the need of working with them. (writing a text document)

But i need help in chosing wich one of them is more worth to buy fore gaming?

As fore Vivo i don´t like those smallest ones 11.1", i´m not much of a gameboy fan .

But i apreciate the widescreen and the nice design.

As stated i´m a complete noob in hardware stuff, so i hope you guys could help me out.

As long the computer will run smothly on nice graphics.

P.S i do not have the highest requierments on gaming grafics, but i like Betafield 2 .
