You're not going to make any great progress on a PC build for that price. Besides, PC tech is changing so quickly, you shouldn't buy any one piece of it until you can buy all of it.
If you're looking for X1 games, I'm a huge fan of Destiny, but it's not for everyone. If you're looking for more of a sure hit, check out Shadows of Mordor or Dragon Age: Inquisition.
If you want to change things up a little, here are some of my favorite purchases (I'm a minor Amazon addict):
A super high quality door-hung b-ball hoop (you'll want to buy a nerf ball with it, the one it comes with is dangerous to valuables in the room)
A classy and useful EDC knife (there are lots of options on this front, /r/knifeclub has great recommendations)
Check out my sub /r/everymanshouldhave for more recommendations like this. It's not super active of late, but it has some great suggestions if you look at the history
