Help with first build to play new first person shooters

This is what I have put together so far. I don't need a hard drive because I already have one with an os on it already so don't need that either. Already have a monitor as well, and don't want an optical drive because all of the games I will play will be downloaded. Any help in keeping this build between its current price point and $700 with better performance would be greatly appreciated. Oh, and the cpu on that list is mispriced for some reason because I called my local microcenter and they said they had it for $40 less.

You need a z77 mobo to overclock.
