Asus Z9PE-D8 WS Dual Xeon Workstation Build RAM Question etc

I'm building a new workstation to do architectural design and rendering. I use:
AutoCAD, Revit, 3Ds Max, V Ray, Rhino, and Adobe Creative Suite. I want to be able to render on my CPU, but I'm really interested in starting to GPU render.

I've been planning this for a few months and really going back and forth on using this MB. My concern was that I've seen a lot of negative reviews on this board, but the people who really know their stuff seen to love it, so I went ahead with it. I'm not a tech expert...more of a dabbler, but I don't mind a challenge, and I’ve never built a system this complex before, so please bear that in mind when answering.

Here are the components that I want to use in my rig, other than the power supply and hard drives I'm not married to any of these, so recommendations are welcome:

2 x E5-2620 Sandy Bridge Xeon processors
Corsair 1000-RM power supply
RAM 32 GB ???
120 GB Samsung Boot Drive
4 x Seagate Barracuda 1TB HDD in RAID 10
Graphics Card: ???

So my RAM question is this: Do I have to buy a quad channel kit to get the RAM to work? if I stick with these processors, I can only use 1333 MHz RAM, and I'm having trouble finding 32 GB kits of RAM on the QVL. I can get 8 GB Kingston ValueRAM and just buy 4 sticks, but I have read that you need to buy a kit in order to run dual/quad channel. Is this the case? I guess I could go to the Ivy Bridge processor and have a much bigger range of 1600 MHz RAM, but that means more money and I'm already bumping into my budget, not only that but then I get conflicted on whether I should just bite the bullet and spend a little bit more and get the 2630s (even more money =/). Another solution would be to just put the 1600 RAM in the system with the 2620s, but given the problems less experienced user have had with this MB, I'm nervous about doing that.

The graphics card is a little bit of a different issue. I can do one of the following:
Quadro K5000 and then put a second GPU in at a later date
2 x GTX Titans
2 x GTX 780 Ti

From what I have read there is an ongoing discussion about Quadro vs GTX and I'm not really trying to rehash that. My preference is to do the 780 Ti. I'm torn between the Titans and the Quadro, so I have to decide if I want reliability and support vs raw rendering power. But if I can use the 780 TI I get more power for way less money and the decision gets a lot easier. The trouble is that the 780 Ti isn't on the QVL... So I'm wondering if anyone is running these on this MB? And if so, do you think I can get them to run without jumping through too many hoops?

If you read this far, thanks and thanks in advance for anyone wanting to tackle this with me.

Input, ideas and opinions are always appreciated.

    Not necessarily. They should work, but it's uncertain whether or not they will work in quad channel.

    Not true. The mobo supports up to 2133 MHz.

    They don't necessarily need to be on the QVL. Asus can't test every single kit of RAM on the market.

    If all the RAM sticks are the same in every aspect, you have a chance of running them all in quad channel, but from what I've seen, it's not guaranteed. I'd be on the safe side and get a 32 GB quad-channel kit.

    The "range" of RAM frequency is just the max supported by Intel for the processor. The mobo can utilize higher frequencies.

    Has there been problems with the board running higher frequency RAM?

    Thanks for taking the time to help! So if I'm reading this right. since the MB can support higher frequency RAM, I can use a higher frequency RAM even though the CPU doesn't support it? If that's the case, I can get a 32 GB quad channel kit @ 1600 MHz and check a few more things off of my list. Out of curosity, do you know if the RAM will then operate at 1600 or if the CPU will bottleneck it to 1333?

    From what I have read, there have been alot of problems with this board. The forums that I have read report issues when OCing the RAM, but I haven't read any issues with the MB not supporting higher frequency RAM. But I keep seeing the same warning "USE RAM FROM THE QVL". For what its worth, Newegg's memory compatibility selector for this board has a lot of memory that is not on the QVL. I'm more trying to avoid running into a problem by sticking to the QVL, but if someone knows a kit that works on this board, I would certainly consider it.

    Thanks again.
