11520x2160=24,883,200 pixels. Where are they getting their 1.5 BILLION pixel math?

Pixels per second, welcome to marketing speak! haha

2x Geforce 680's should be more than enough for triple 1080P screens, provided your PSU can keep up. (The article was only running a 750w potentially no-name PSU on 3x Radeon 7970's and wondered why they ran into problems, not to mention the crap Antec 900 case.)

Essentially, just keep adding a Geforce 680 untill your performance is adequate.
But even at 5760x1080 you might be pleasently surprised how many games you can run at 60fps with a single Geforce 680.

Thanks for the info!  I'm pretty sure I have a 750w PSU.  That's should be enough or should I try and find one that's over 800w just to be on the safe side?

PSU wattage *is* important, but the brand/quality is just as important too.
For example a Corsair HX/AX can easily output loads greater than they are advertised as. (I.E. 850w outputting 900w etc'.)
Where as something like a 1,000w Shaw PSU will literally catch on fire if you even try half of it's rated load.

I ran my system on a Corsair HX 850 for months with my current set-up, granted I did some undervolting to lower power consumption.

Plus, if you want to save energy, getting a PSU that's power efficient at your systems idle/load can be important to.
