Hi capmeo23.....Welcome to the forums.
Couple of things...need to know what size monitor and resolution you play with.
The X79 platfrom in Dreadnought level 3 is really more than you need for gaming. It's quad channel memory and the i7-3930k 6 core cpu are more for video editing, rendering, 3D modeling and other apps that suck up RAM usage. Nothing wrong with it and if budget allows then go for it.
Start with the Dreadnought level 2 , go with sli, 2x 670 and see what you think. If this is a rig for 23/24" monitor with 1920x1080 resolution then the sli 670 will max out the gaming for alot less( $500) than sli 680 and almost the same performance.
With the hafX case, you picked the best for air cooling.
Those Zalman fans are very noisy and not needed with the HafX case, which is great as-is.
Hope this helps.
Here's the build I was talking about. Thought I had to go but not for a few minutes.

I believe this would be about $900 cheaper for the same gaming on a 24" monitor.
Good Luck
