I have been trying to make this work for me but I'm worried about the difference between 2600k and this.
If you could go back and do it again, would you buy the 3820? go bigger? or back to 2600k?

2600k is old news, Ivy Bridge is all hype. I think for anyone wanting to go "bigger" the 3820 on an X79 platform is the best option right now because in 2013 they will be able to get Ivy Bridge - E 8 core/16 thread CPU's, which is going to be insane overkill but totally awesome.

Main reason I choose a 3820 is because I don't like how the 2600k platform is limited to only 16 PCI-E lanes (8/8 in Crossfire).

Thanks for the reply man. Yeah, I feel the same way that if i got SB/IB now that I"ll be limiting myself. I plan on running 2 cards in sli/xfire eventually and would like the to run at x16 for both. Plus, if i decided to upgrade i can go to the 3930k and its'll be plenty.

Thanks again man +rep

Ya, everyone likes to say that 8/8 is enough but I noticed people only started complaining about "microstudder" starting with the 1156/1155 platform. It's totally unsubstantiated and just a personal theory but I would just prefer to have full PCI bandwidth going to my 6950's, maybe 8/8 is enough for benchmarks but I think 16/16 would give smoother performance.

Another reason you would be limiting yourself with Ivy Bridge on the 1155 platform is that after IB Intel is going to a completely new socket so you would have no upgrade path.

Again, What you speak is true. I figured with this socket i can get atleast another 18 months out of it, and still have plenty of room to grow. I have a single 6950/6970 right now, and I plan on adding another as soon as I can get my hands on it.

^ pretty much the only reason I went X79.

Finally decided it's time to get something shiny new. Going to order a 3820 sometime tomorrow but I'm still unsure of what motherboard to pick, something along the lines of an ASRock X79 EXTREME4 or GIGABYTE GA-X79-UD3.

I just built a new i7-3820 rig with a Sabertooth X79 board and I'm very happy with it, if that helps. I was able to OC it pretty easily to 4.75Ghz with only a corsair H100 cooling the chip. Hope that's helpful.

what did you enable and disable? are you getting your factory target in ram?

I disabled all downclocking and thermal options. Using the 125 strap X 38. XMP for the ram, running at 2000Mhz. (rated speed for the ram is 2133 so, no it's downtweaked a bit) I believe it is possible to manually achieve the rated RAM speed through advanced tweaking of the timings and voltages but I haven't had time to really mess around with it all. A new BIOS was just released in the past couple of days so maybe it's easier to accomplish than it was before. Haven't tried to push it any further either, but I'll bet this chip/board can go a lot higher in terms of overall clock speed. Idle temps are around 31C at current settings.
