Is this a good laptop for what i want it to do?

Hello,im currently in the market for a laptop and i found one that interests me; however, since i am a computer newb im not entirely sure if this will meet up to what i want it to do.

here is the laptop:

and what i would like to do is be able to play games on it, more specifically: Starcraft II, Call of Duty: Modern Warfare II and eventually Modern Warfare III and if possible, put my playstation 2 emulator on it.

battery life isn't an issue for me as everywhere i intend to use this laptop will have an outlet (school, home, work)

thanks
