Is this a good build?

[justin88]

I am new to building PC's, in fact this is the first PC I have attempted to build. Overall, I would like to be able to play the newest PC games at high to ultra settings while recording the game play and maintaining 120 frames. I have posted my build below, I would appreciate any criticism or helpful pointers. Also, is my PSU high enough or do I need a higher wattage? Thank You.
I am also building a computer from scratch, I own a laptop so I have to purchase everything. So, I'll post my build, with additional options, than I'll talk about that build.

HS (Heat Sink): Noctua 6 Dual Heatpipe with 140mm/120mm Dual SSO Bearing Fans CPU Cooler NH-D14 - $80

You don't really need a 3770K for your uses and the 680 isn't really necessary when the GTX 670 uses the same processor and is $100 cheaper.

Here is what I would suggest:

Then with the difference add whatever monitor, keyboard, and mouse you want. I don't suggest those things as they're mainly personal preference.
