i'm buying this laptop in the next few weeks and i wanted to know is this good for gaming.
i want to play games such as gta 4, minecraft, dirt 3 and driver san francisco.
would this laptop be good for it. I don't want to play them on max resoliution but at least at low-medium graphics

HP Pavilion 17-e019dx 17-Inch Laptop
amazon Price:$468.9
Price lower than you give.

For the record, only high end laptops with exteral graphic card are good for gaming. That laptop is capable and it will run games like that with lower settings.
