Is this a decent gaming PC? Looking for a reliable PC that'll play games like H1Z1, CS: GO, GTA 5, etc?

Price is $759 + tax which totals $821.31. Other than a monitor and speakers, which I already own, this should be everything I need right? I do not have the time or experience to build my own so please if you give other alternatives, pre-built only. I'm looking to play games such as H1Z1, CSGO, GTA 5, etc. Details:
