Here's my upcoming build, it'll be my second build, but the first that I'll do alone.
Case- Corsair 500r
MoBo- Asrock z77 Extreme6
Processor: i7 3770k
Cooler: Corsair H100i
Graphics Cards: 2x Asus Direct CU II GTX 680's w/ 4Gb
HDD: 1TB WD Black (looking to buy a 128 or 512 SSD in the future)
RAM: 16GB (8GBx2) of G-Skill Ripjaws X Blue @ 9-9-9
PSU: Corsair AX850
DVD Drive: The Asus $20 DVD Drive on newegg.
(Hopefully that's everything, if I'm missing something, pls lmk)
My main question: Is this a good build for a bit less than $2200?
Second question: Will the 850watt PSU be able to hold all this down, and in the future, one more SSD? (Maybe a bit of overclocking, but nothing too extreme, minor stuff
The build looks good; I would increase your PSU to 1000w unit for more system longevity
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.
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.
