[strike][strike][/strike][/strike]Bring your wife when you go to Microcenter otherwise you will walk out 3 hours later with a shopping cart full of $700 in "necessary" peripherals. That's why they sell the CPUs so cheap.
5820k $300

Gigabyte UD3 x99 MB $179 after Mail in rebate. They may still have the $20 off CPU/MB combo discount.

Use that $20 to get a better MB or the 2 year protection plan.
16GB Corsair DDR4 ram. 4x4. $109. Or whatever your favorite is.

Total $588
Your total was $606 for CPU/MB/RAM and now you have 50% more cores on a high-end platform.
You have some wiggle room to upgrade the MB to a level you are happy with or maybe get 32GB ram for about $200.
I initially bought a MSI x99s Gaming 7 open box for $148 with MIR/combo discount. It ended up having some issues with the USB ports so I took it back and went with the Asus Sabertooth for $300. One big difference you will see with these boards is most of them have a revision that includes USB 3.1. Sometimes on the board and sometimes as an add on card, but the premium for that is $75-$100. From the x99 reviews on this site and others all of the x99 boards are good, they just make certain compromises on the configurations.
I honestly don't know what I was trying to say about the PSU other than don't get a cheap cS/CX corsair
Here is a good Tier 2 Seasonic 550w semi-modular for $79

EDIT: scratch that, I am contradicting myself here. Opps. What I meant was corsair and XFX have some lines that are made by Seasonic and get rebates frequently so you could still get a quality 850w or so PSU for much less than $100 if you put some work into it. Go look at the PSU tier list in the stickies at the Components forum. Keep an eye on r/buildapcsales. Sorry,no am tired.
Check the deals on newegg daily and I bet you can get an equal quality/more wattage for less within a week with promos/rebates.

Here is my build if you are interested. Still can't decide on 16 or 32GB RAM, I really want gsync or free sync on the monitor so I will probably send the unopened Ben Q back and wait for the Q4 releases. Definitely waiting to see what happens with the Samsung 950 M.2 drives in the next month, may just get a big 850 1TB on sale over the holidays.
You now have lots to think about.
