First of all, link your build correctly. Copy paste from the permalink in the top left box. Like this:
http://pcpartpicker.com/p/vnNtXLThis build I linked is close to what I have in my build right now. The processor is just a newer model and this keyboard has Blue switches instead of red. Obviously this is over budget, however, this is beneficial. Now you can see a complete build and decide how you will "trim the fat". That graphics card is $323. Maybe we move down to a 9TX960. Or a R380. Now lets look at the motherboard, there are many less expensive options. I put that WIFI card into my PC just last week and let me tell you, its worth it. My dl/up speeds are killer.
Lastly, specifiy the types of games you are looking to play? If you are into League and such, this build is overkill. If however you are wanting to play Witcher 3 doing 4k at 60fps. a) You'll need a better card b) You'll need a better job.
