Can this laptop run current games (AC4, COD ghosts, etc)?

It's a Lenovo ideapad g505s. Can it run new-ish games? What about coming games like AC Unity? I don't understand what the specs mean, so I don't know. Also I need something under $500, so don't tell be to get an expensive PC

In short no most likely it will not be able to run new games like you would want to run. You could get a desktop for the same price that could do much more or just get a console if you do not need a pc and just want to play games.
