Sounds good, Dark and a 4930k is the direction I am going.  Also, this is the RAM I was going to go with, and I am going for a OC that is 24/7 Stable.

Talk to Nateman for a VRM block for your Dark, when you clock them, they get pretty hot otherwise.

I noticed that heat Dave.  Been playing with the Dark the last few nights.  A simple fan took care of the problem.  NB Chipset gets way hot too.

Well, I'm Almost Ready to order the X79 Dark/4930K/and the G.SKILL Trident X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 2666 (PC3 21300) Desktop Memory Model F3-2666C12Q-32GTXD, But First I need to talk to Nate and see what LGA 2011 CPU Water block he recommends to use with his VRM Block/Barbed fittings to ensure a proper fit before I commit!

Well, EK Supremacy as well as Apogee HD will work too.  Maybe get the air cooler waterblock from Nate.....

You have a EVGA Dark board Q?

Yep, you got text

What does Nate's Air Cooler Water Block Look Like?

Decisions, Decisions........What to Do, What to Do........
 
I'm Sure Everybody Knows I've been Building My Rigs Over the Years Strictly for Benching and Reaching Out for Every Point I can Get with Mainly EVGA Motherboards/Graphics Cards and other EVGA Products. 
 
But Honestly, While I Do Know What CPU/Memory I want to use, I Just Can't seem to make up My Mind on whether an EVGA X79 Dark/4930K would get Higher Performance/Benching Scores than an ASUS RIVE/RIV BE/4930K!
 
Lately I Keep Going Over/Looking/Analyzing the Futuremark Scores/Statistics, and Even though there are More of EVGA Graphics Cards used for High Scores in the Hall of Fame, They are Also being used with ASUS RIVE/ RIV BE Motherboards!, And Please Don't Hate Me for Saying So because I have ALWAYS Used EVGA MB's and Graphics Products since 2008!
 
Maybe I Need to do some more Research Before I Actually have to Commit Myself to an Insane Asylum!
 

Well the RIV BE is overall probably the better board. The real question would be can you afford to spend that much extra on it. You could get the dark and one of Nate's blocks for probably about the same price. I have no idea what his prices are only speculating. I would say your overclocking potential and benching scores would be more luck of the draw with your CPU than which top of the line mobo you chose.

Asus Rampage Extreme has the reputation, for many years, for being the extreme overclocker's board.  Evga broke into that realm with the 680 if you remember, then gained ground with our beloved Classified 759.  Seems like everyone had a classy, but then R&D team left Evga, so everyone went back to Asus.  I've had a number of Asus boards in between.  
 
Only a few extreme folks use the Dark, but not because Asus is better.  There were some BIOS issues with the Dark to begin with, which didn't do anything for evga's rep.  They are pretty much ironed out now.  And truthfully, those were issues that a guy like you or I could care less about.
 
The RIVE is hit or miss.  A high % of the boards are RMA'd. If you get a good sample, you're happy.  Otherwise....  The Black Edition is too expensive and everyone already has a RIVE.  Sham and Andre left Asus.  Vince bleeds Evga, so we'll get good support there. 
 
I already know the Dark is just as good as the Asus counterpart.  The data and users on my team already verified.  And TBH the mobo isn't going to be all that important in the hierarchy of critical components.  It ain't gonna make a bad chip, good, or a good chip better.
