This is what I'm looking at for upgrading my computer. I've got $3000 to spend on a new Gaming PC. Here are the parts I currently have in mind and I'd like to know if these would make up the fastest, most powerful computer in terms of components for the money I am able to spend. It currently adds up to $2792 so I have some wiggle room.

No it is not the fastest for gaming. You would be better off with something like a 3570K and then get multiple video cards instead of just 1 video card and a 6 core processor. You know, because it is your video cards driving the graphics/gaming experience moreso than the processor.
instead of spending 850 on the cpu/mobo, spend 350 on the cpu/mobo and do a GTX 690 or 2x GTX 680.
Stick with 8gb of ram, or just 2 sticks 2x8gb for 16gb total so that your overclock is more stable.
A few ways to save money and still not suffer performance loss:
1) The i5-3570K is just as fast as the i7-3930K for gaming. Where the 3930K shines is CAD, heavy video rendering, or running a lot VM's.
2) 8GB is enough for a gaming system. 16GB max since it's at most $100 for a good set of 2X8GB of RAM.
3) No need for a separate LAN card these days unless the one in the motherboard is dead.
4) 1200W is overkill for one GPU. A good 750W is more than enough
At most, $1500 will get you a nice gaming system these days. The problem with going higher is in one year, your $3K system will be outperformed by a $1K system. If you're going to spend $3K on a system, get a really nice monitor at least, and save the rest for upgrades.
You'll notice that Shogun 2: Total War is very CPU limited (means frames increase with speed of processor) You can see that the 3570k stock is faster than the 3930k stock. At the same speeds they would likely perform identically. 3570k is enough.
personally for 3k i'd got 3570k, 670 sli (or maybe a 680), 16GB (its not expensive) for about 1500, and then buy a 780/880 when they come out and spend the 3k over a 2-3 year period. then at the end of the 3 years you'll have something that would last for another 2 years as very high end. Your current rig in 5 years will be mediocre.
PC's are money pits, lots of small upgrades will get you a better deal often.
