I like to play games like CS:S, Garry's Mod, Minecraft, CoD, GTA and some other modern-day shooters and RPG games like the Battlefield series, and Skyrim. I was wondering what games this HP laptop could handle... I will also use this laptop for school, (lectures, typing papers, etc.) and basic things like youtube, facebook, NGU

I know HP Laptops aren't the best for gaming, but my dad works for HP so he gets a good discount on things, and he's cheap.
