PSU and graphics card help

[poklumytu]

I'm building a gaming pc right now http://pcpartpicker.com/list/Vqnkcc (no graphics card yet)
I'm wondering if a 550w power supply is enough to handle this build.
Any recommendations for graphics card ($150-250)? I want to be able to stream lol/overwatch/csgo
Thank you.

An i5 6600k will be more ideal. That PSU is Tier 4, get one that's Tier 1 or 2. Already bought some parts? What is your budget?
