I think that was a pretty obvious answer.... the 3930k 6cores are beasts.... It actually benches better than all of the SB chips... So I don't see how you can say it will hinder my gaming capabilities(no offense). it's the best available right now.. And honestly I think the IVY series are going to be the new moderate tier of intel... like SB was... And the temp situation is not necessarily true. The 2011 cpu's run very hot compared to 1155. My job requires me to use a lot of rendering software as well... One of the main reasons I wanted a 6 core processor
You were likely bottlenecked by the fact that your Sandy Bridge board only allows your cards to be run at 8x/4x/4x. Sandy bridge only has 16 PCI-Express lanes. Sandy Bridge-E will allow you to run at 16x/8x/8x, as it has 40 lanes available.
Your anecdotal "I seen my friend" results aren't really conclusive. There aren't any games out there that will take advantage of 6 cores vs 4 cores. You might see some that take advantage of the increased cache (WoW, etc), but that's about it.
It certainly is the "best available" right now in terms of multi-threaded applications, heavy rendering workloads, benchmarking (hyperthreading w/ 12 cores), but you seem to have conveniently ignored the fact that it is a ring bus running on 6 cores - if you don't understand this you should probably check out a few references on the subject.
SB-E is only slightly better core-for-core, and if you aren't overclocking it any further than 4.2, you won't actually get any of the benefits - a similar sandy bridge chip will hit 4.5 effortlessly, and up to 5.0 and beyond. You will have trouble passing 4.7 or so without hitting thermal barriers with SB-E.
If you came here to brag and show off your credit limit, I understand. But if you came here to receive critiques and suggestions on your build and ideas to get more for your money, we're all here to help. I just simply don't believe you got your money's worth in this case.Summary for tl;dr:
You'd be much better off spending your cash on supporting components (WC loop, or case that's better for air-oriented cooling, Sandy/Ivy Bridge parts that suit your needs better, etc)
