Lenovo G505s is what I sue and it will run anything I throw at it and it was cheap. It does run hot though the G50 uses Intel and Nvidia is better but more expensive. Best thing to get is probably an ultra book...

You will be able to find one without a graphics card that will be cheaper but something that has windows and is built well.
