It may be able to "run" it but not play it. Much like a VW Bettle, "can" tow a boat, right before it's rear axle falls off.
Since you have a laptop, the only choice you have to play real games is to replace the laptop or get a deskotop for gaming. The NV79C50U series has a real graphic card you can use for games http://www.gateway.com/systems/product/529668736.php
Unfortunately the laptop you picked is a dog for games.
