The new socket 2011 should be coming out soon i think, i know that a couple of online stores in aus are starying to discontinue suppling current 2011 parts
ivy-E is coming out in september, might as well wait until the ivy version of the chip I suggested comes out as they are gennerally the same price and don't lower
I would think so. You would have 3000-3500 per system (or how ever you wanted to divide it up) if you went that route.You would probably end up having one with two lower clocked 2011 6 core xeon processors 64gb of ram and a titan while the other would have an overclocked 3930k 32gb and the less expensive quadro k4000. That would be my guestamate of what would be possible with that budget.
I really like gigabusters suggested build also.
Ivy bridge E is not really an option because it would take to long for the Xeon version of that chip to come out
then go with the xeon sandybridge-e since you're obviously not worried about a outdated CPU since you were originally going with 1366
however, I wonder if getting a second titan, and 2400 mhz ram have greater impact than having an additional cpu?
no, core is king in rendering, GPU aren't as important as CPUs, one titan will suffice
ah. figures... lol

If you really want xeons, get them, but get two 8 core one's and get a cheaper GPU. If you want a good AMD GPU get an AMD FirePro S10000 ($3500): http://www.newegg.com/Product/Product.aspx?Item=N82E16814105005&Tpk=AMD%20FirePro%20s10000&IsVirtualParent=1
Or get a Telsa GPU for nVidia.
I put a sound card in as it was a workstation and I intended the 60GB SSD to be used as a cachr for the 2 seagate 4TB constellation drives. The other two SSD's were going in your RAID preferance.
BTW these are just ideas
