I don't know much about bottlenecking. Please don't accuse me of it. I'm also not a fanboy.
Are you looking for an opinion? To be honest, these builds don't make too much sense to me.
I would go with this if I were you. http://pcpartpicker.com/p/BhuB
Also I would get the nzxt phantom 630 black instead of the color they have on their

Also I don't see the point in memory faster than 1600mhz because you see little to no benefit for the extra money you spend.
Those are some of the strangest builds I have ever seen...
I assume you already have a good monitor/keyboard/mouse setup, seeing as you didn't include any in the build. At that budget, you will want a really nice case. The Silverstone TJ11B-W case fits the largest motherboards, XL-ATX, and has some of the best build quality out there. For $500, it is a steep price, but it offers the most expansion for water cooling and any other upgrades you can think of. At the current state, 2 graphics cards aren't going to benefit you that much in gaming. The FPS will jump if you are using multiple GPUs, but on a single monitor, the increase won't be visisble. If you are using Adobe software, you will want Nvidia cards because of their CUDA cores. When you aren't satisfied with the performance of the GTX 680, you can upgrade to something like the Nvidia Titan or an SLI 680. The Intel 3960X isn't worth the $500 more than the 3930k. If you overclock the 3930k, you can reach or surpass the 3960X - they are practically the same thing. The best pre-fab CPU cooler is the Swiftech H220, allowing for upgrading to more radiators, pumps, water blocks, radiators, etc. Here is what I came up with: http://pcpartpicker.com/p/Bhr0
8 cores, large 4GB card will help out in rendering
you might one to wait until ivy comes to 2011 here pretty soon before you put nearly 2K in a CPU
you actually see a huge difference in rendering since its memory intensive
This thing will be madness! I'd get a better PSU though. It'd probably be worth it.
