I'm buying an inspirion 6000 myself (1.6ghz, 1g ram) but I'm getting my own video card. I don't trust the integrated graphics for anything, video editing or gaming. If you read my own post about the laptop it explains I'm going to buy my own video card (an ATI mobility x700) which is the midrange card. It actually cheaper than the one listed by dell. Though shipping availability might be hard for you. I'm willing to help you out if there arn't any people who ship to Malaysia.
EDIT: You're also going to have higher resolutions with a dedicated graphics card
