Time to build a New PC. Here again for help. 600-800$ budget build.

So I have always got great advice/Help here so im back before I start buying things randomly.
I want to build a new PC that I can stream with. I want to run a 3 monitor setup for streaming on my PC and Xbox one. Want to to be capable of play most if not all new games, but mainly i play WOW, League, H1Z1, etc. nothing to demanding.
Right now i have an intel i5 3330 with a Intel DZ77GAL-70K motherboard.
G skill Ripjaw 8GB ram (actually only 4 becasue one stopped working)
Asus GTX660 Ti 2GB GPU
CONSAIR CX600M PSU

I have about 600-800 to spend so im wondering what i should buy to make it stream capable and just all around a good 2015 computer.
I figure I need an i7 with a new board and a better graphics card. (not sure if i can run 3 monitors with one card or would i have to run 2)

Dont need HD or SSD or Disk Drive, or Case. I may be able to even keep my PSU?
Anyways let me know what you guys suggest I buy to make this thing kick ass again

Just upgrade your GPU to a GTX 970, and PSU to whatever the crap you want (just make sure it's good), and you'll be fine.

do i not need to worry about a motherboard or processor upgrade yet?
Can one card run 3 monitors, I run 2 with one but havent ever tried 3.
What size PSU should I at least get

 

[Majestera]

get a 700w or 750w 80+gold

3 MONITORS?!!! GAMING?!!! GTX 660 TI?!!!!!!

Alright, you need to spend >$1000 for this. It's official. A single i5, any generation, would not be able to handle 3 monitors. And gaming.

i mean right now i run 2 and its fine on my current card.
I SHOULD RESTATE IM SORRY lol. only playing games on 1 of them. just have other windows, or internet open on the other 2.

Ohhh.... Phew... You scared the $[-]17 out of me for a sec!!! xDDD

Alright, then a GTX 980 and a new power supply. Make sure to grab 8GB more RAM along the way. Then 3 monitors easy.
