You didn't mention what you wanted exactly for the $5k and what you work with, got a gopro camera also btw ?
I got over the $5k because of the monitor but much better/cheaper monitors will come out this year, maybe the 40 inch Philips would be a nice one if you need to work in 4k ? I myself wasn't aware that asus also had a dual 2011-3 intel c612 boards on the market already, perhaps you need one with 16+ ram dimm banks ? I mean if you buy a beast of a machine you want expansion possibilties right so dont save on the motherboard I would say. RAM and cpu's will get cheaper or you come across a second hand ones in the future ? If your machine gets slow just add extra ram or another/other cpu.
BTW you can also look at intel motherboards if you need the extra ram, but I am not sure if they also support SLI/crossfire. But intels quality/support/documentation is very good. I would buy it because they will deliver stickers for the inside of your computer case, which can be very handy.
I think you can save a few hundred bucks on the cpu and ram, case and power supply. And graphics card (dont know what need exactly?) and the output your monitor/screens. And this doesn't even have a mouse and keyboard and also a bigger storage device, btw an m2 storage for the OS operating system is probably the best investment for your money, the samsung m2 pcie 512 Gigabytes isn't that much more expensive but looks way better ofcourse. Let me change that!

The pc parts picker mentions that the motherboard and the Samsung SSD aren't compatible but asus mentions it compatible on their website: http://www.asus.com/Commercial_Servers_Workstations/Z10PED8_WS/HelpDesk_QVL/ good to read that btw if you really going to order a systems such as this. Here is another URL about the drive: http://www.thessdreview.com/daily-news/latest-buzz/ssd-week-samsung-xp941/
[video="https://www.youtube.com/watch?v=OoxdNZ64HhU"][/video]
And it also mentions that the graphics cards could be too big for the case, then you need to buy a bigger one maybe the 900D (much more expensive and heavier) or another one.
This company builds a rackspace server around this motherboard, maybe wise to have a look at: http://www.ico.de/server-konfigurator/bto3.php?gruppe=ybto33&level=&typ=
BTW that information must be wrong it says 1 socket cpu also when you click the PDF, but I found it with a google search and got this PDF:
http://www.ico.de/img/pdf/i4ag4a.pdf and there seems to be the right information.
