Questions for my upcoming build

The build looks good; I would increase your PSU to 1000w unit for more system longevity

whats ur country of origin and maximum budget in ur country.

also do u need monitor+key+mousse+os thanks.

Could you suggest any good 1000 Watt PSU's? I picked to stay with the AX850 because Corsair makes kick ass PSU's, but I'm pretty sure they don't sell any 1000 watt PSU's, and the AX1200 goes over my budget, but if need be, I'll save up a bit more money if it's worth it.

I do have a monitor, and mouse, but I need a keyboard, and I'll be looking to gt a nicer monitor in the future since the one I have is like 5 years old now. I also got the OS and country is USA

no need for 680s. and 4gbs of vram is useless for a while in games.

What kind of monitors are you using ? What resolution ? If you aren't gaming at 2560x1440 or trying to surround game at 5760x1080 then you certainly don't need two 670s or 680s. If you don't have a 27" 2560x1440 get something like the iceclock build above and add one of those Korean monitors off of ebay (or check monoprice.com or microcenter if you have one, they sell them for a little extra markup).
As far as power supply, quality 850watt is enough, and you can add as many drives as you want -the power draw in the system is all going to be to the video cards - SSDs & even normal spinning platter hard disks barely register.

Ok, I'm getting the two 680's, because they're awesome ass cards, and in the future I will be running a 3 monitor 2560x1440 setup.

And no, this build isn't just for gaming, it's primarily for video editing, so I need rendering as fast as possible.

except I don't have a microcenter anywhere near me...
