I think the only folks who will be able to even compete with this for worst performance/$ will be the custom loop guys. Though that's a stretch. There's nothing but top notch quality all over the place in this build, however, I would argue that one could build TWO machines in a very similar performance bracket for the same price. One could then have machine redundancy and a potential compute "farm" unit for productivity apps.
I put a ton of research into my purchase choices, often second guessing my every decision.
I don't mean offense here, but I think you should have spent some more time researching and second guessing. The build you have created has an outrageously piss poor performance/$, even worse when you consider the non-gaming nature of the use.
A $470 gaming GPU for someone who works in media content editing? A $100-200 gaming GPU would have been fine here to keep the door open for "potential" gaming at very respectable settings. The GTX680 won't do much good for the big picture here, and as is typical, flagship cards are very over-priced for their performance level. This is no exception. The responsible choice here would have been either a workstation card, or a GTX650Ti or HD7770 at the highest end.
The 3570K is a gaming CPU primarily. E3, i7, or 8 core piledriver are where the value is for a workstation rig.
1200W PSU: Even if this machine is SLId and overclocked, it will likely never use half of this. This is a terrible waste for the purposes of this machine. There are so many good quality, well made high efficiency units available now under $100 that would power this system. I don't understand this approach. Intel CPU and NV GPU on latest generations is "LOW POWER CONSUMPTION. The machine in question here, won't use a quarter of the PSU chosen. SLI isn't even something to consider here, since, this is primarily not a gaming rig. A 450W Capstone for $60 would have been a perfect match here.
