Yeah the build looks nice in most parts,
But there are a few thing I'd like you to consider:

* Get a better GPU.
* Get a better PSU brand like Seasonic or XFX and as @nashdes001 said, a 650W is enough but a 750W will leave an opening for SLI.
I've built it here on your own build and added a better motherboard as well:
