Need Help With New Rig

[pcamat]

Currently, I'm a college student nearing the end of my freshman semester and I'm looking to build a new gaming PC. My budget is anything around $1700 and I would like to play most AAA title games comfortably (70+ fps) at 1440p, I don't want to have to worry about overclocking but would like to have a PC that can do so as needed. I would like to run video editing software and photoshop as well. I've put together a rig that sits right under that $1700 range and was wondering if you could offer some feedback?

Feel free to criticize as harshly as you would like, I am relatively knew to this sorta thing and am still learning! Any feedback is greatly appreciated.
