Dave recommended the P9X79 Deluxe for my rig and I've been loving it. Since I initially flashed the BIOS I haven't had a single issue with this board. It will scream no matter what SB-E chip you drop into it.

If it's really that important you should be running a Xeon with ECC memory if you really don't want corrupted data. Honestly SB-E can push reasonable clocks without a hick-up, you just have to ensure its stability first and not go too gung-ho on the voltages and clocks. Either way an OC shouldn't be needed, a 6-core SB-E will throw down just about any CPU currently out with these workloads any day and really is worth it. Just imagine what IVB-E will be able to do when that comes out as well.
With all of that said, I have a 3820 and I'm perfectly happy with it and its a good option if you don't want to spend twice as much for only 2 more cores or if you plan to move to IVB-E when that comes out but if you're going to be using this professionally, just invest in the 3930k.
I guess my question is: You said that you will be using this for not just gaming but for various other applications that utilize more cores/threads very well. What will you primarily be using this for? Is it going to be a work machine that you professional use with occasional gaming, or will it primarily be for gaming with occasional CAD and CG?
