i am getting a new laptop since i am going to college next year could anyone give me a suggestion on viable gaming laptops under 1500. i found one alienware with ati 1800x 256mb for 1400 but i need more choices.

i have an ATI 9700 mobility 128mb with 512ram and 2.0Ghz processor and my laptop runs the demo well with 1440+900 high texture and animation and low AA with no shader. If I can run the demo with mini lags i should be able to play the full version right?
