Here is a better configuration with explanation:

Explanation: Why I told you what I told you. I want you to have the best system possible and this will definitely meet that criteria. It will have the latest hardware and trust me, if you decide not to build it as it is above, it might not be compatible. I noticed a few weird things in your parts list.
Motherboard: This is one of the best motherboards on the market today. There is nothing this board doesn't have. With the inclusion of thunderbolt connectivity, you can be transfering files at up to 10x the speed of USB 3.0 with a compatible device. This motherboard will also provide full 16x bandwidth to both of your beastly graphics cards!
Monitors: I know you probably want nVidia 3D vision and you can have that with the ASUS VG278H. This monitor uses a much higher quality panel for increased color accuracy. The ASUS PB238Q is a business style monitor that will add a certain clean, professional aesthetic to your system. Both options are very high quality monitors and the easy way to choose will be to ask yourself if you want 3D or not.
Processor: This is the latest, fastest processor from Intel on the new Z77 platform. The 3770k is $700 cheaper than the 3960x for near the same performance. The 3960x runs on the X79 platform which is LAST GENERATION!!!!! You would be building a system that is already outdated.
Memory: There isn't much to say about this one. It is fully optimized for the motherboard that I have suggested and because there will only be two DIMMs, you will be able to have a more stable system at higher overclocks.
Graphics Card(s): These cards are a great choice! There is an EVGA GTX 690 Signature Edition, but the difference is that it is $50 more and includes a T-Shirt. It is your choice.
Storage: The Samsung 830 Series has crazy high performance and is a great choice for a build like this. The 2x 2TB WD Caviar Black in RAID 0 is a little much, but it certain will match the lunacy of quad SLI. Again, great choice!
Power: I didn't know which one you meant specifically, but this is the one I have powering my system and it is tried and true. You won't find a better 1200W power supply.
Optical Drive: I went ahead and added one for your convenience. In my opinion, everyone should have one, and a Blu-Ray burner is a great way to get every feature you possibly can into one drive.
Sound Card: I don't care what anybody else including yourself tell you
, any gaming rig, and for that matter, any computer at all should have a sound card. It doesn't have to be crazy expensive, but something to process the audio and give you a more immersive experience. I would think that when you play a game on a triple monitor setup, that you want an explosion to sound like an explosion not a speaker crackle.
Case: Again, I went ahead and made a recommendation for a case. this one is a great choice. It is a medium size and will suit your build quite well.
Processor Cooler: With this cooler, and the unlocked 3770k, you will be able to boast an overclock of upwards of 4.4GHz. Trust me, you need it.
I hope this helps, and I would love to hear how this system turns out. I know there is a lot to read, but every bit is important. Have Fun!!!!!
