Im kinda new to this pc building stuff.. if anyone could give me some pointers on what should i get or is this good enough?

I normally play FPS games like Modernwarfare 3 or Black ops or BF.. and at the same time i want to edit video or stream on twitch if possible.

for a 1200$ USD you can get better build than this.

Edit:
This is what i personally liked for 1080p gaming @ 60fps AVG in most of new games (High-Ultra Presets) and would do good with Editing and streaming + SSD would support you in good recording of gameplays.

This build will support and give good room for Overclocking , in case you dont want to do that , you can change processor to a lower version or just a non k ( i5 4670 ) and motherboard to differnt one.

i added a 650w PSU, in case you wanna OC and add another GPU in future -CrossfireX
1TB will be fine but you can get more in future , also SSD can do alot of improvement if you install OS and few games on it or use it as secondry device for recording gameplays.
just some basic information , good luck!
