I would say P67/Z68 (1155) is the route to stick with right now unless you really need more than four cores. I found this post
the other night on the Anandtech forums and I completely agree:

In the case of X79 vs. Z68 the total platform is largely a wash, and without absolutely needing the extra PCI-e lanes, I'd even go as far as
saying Z68 is a superior platform/chipset because it actually supports SSD caching whereas X79 does not (seriously, wtf)

X79 was supposed to be a beastly chipset and make s2011 truly stand apart from 1155 with up to 10 x SATA6 ports including support for
SAS and its own 4x PCI-e channel connection to the CPU to provide plenty of bandwidth for all those potential hard drives

Then it was like Intel said screw it, AMD can't compete so lets just rip everyone off by not advancing our chipset/platform at all and charging
everyone an arm and leg for it regardless. Seriously, as a chipset X79 is ultimately no better than P67. As a platform s2011 does offer
advantages such as 6+core CPUs, quad channel memory, and extra PCI-e lanes, but that's all in the CPU now...so why is intel charging
so much for X79 and driving s2011 motherboard costs up?
I mean... I would ultimately look at what you need to accomplish outside of multiboxing World of Warcraft -- The 2600K (or
2700K) can accomplish quite a bit and has a lot of room to OC the shit out of it for much cheaper than an X79 system. You'll
probably want to spend the money you save buying an 1155 system on the new 28nm GPUs this year.
