Yeah, it will be fine for playing games. If you want a quad core CPU, then you basically need to step up to $700, but that also bumps you up to a GTX 960m which most hardcore gamers believe is the minimum GPU you should shoot for if you want to play games.
That's a good find. It would be nice if the dedicated GPU was actually listed in the description; it seems to be a GTX 950m based on the comments. That is probably why it did not appear as a search result.
