|Yeah, like Mick said... thats an integrated graphics chip. Not only that, but most laptop graphics cards cannot be overclocked. This is because that generates extra heat and power consumption, and usually the laptop components are not made to handle them. IF you overclocked your mobile GPU, you stand a high chance of melting your motherboard (which it is usually soldered directly to). Fortunately, most companies lock the cards and therefore they can't be changed.|
In other news, laptops are terrible investments for gaming machines. In your case, you don't even have a gaming laptop. You have an ultra-portable machine that is made to do basic tasks, gaming is not one of them.
If you want to game, the best cost option is still (and probably always will be) a desktop.
