Hi there, I'm completely new to PC gaming and know nothing about it. Therefore, I would like to buy a PC with limited complications which is why I'm not looking at doing a build just yet. I've found this one http://www.ebuyer.com/764291-asus-g11cb-gaming-pc-g11cb-uk010t but will it be able to run games such as GTA 5 without them lagging or being unplayable? Many thanks
