Our last known single-threaded test, iTunes, demonstrates the 100 MHz advantage that Core i7-3960X boasts over Core i7-2600K with only one thread active under Turbo Boost. The Core i5-2500K follows right behind, trailed by Core i7-990X.
Based on the age of the other CPUs in this test, the only real loser is FX-8150, which just came out, but cannot outpace the three-year-old Core i7-920.

FX-8150 performs more admirably in our MainConcept transcode job, where it not only bests the i7-920, but also the other two AMD processors tested and Intel’s Core i5-2500K.
It cannot overtake the -2600K, -990X, or -3960X, though. In fact, thorough optimizations for threading allow Sandy Bridge-E to take first place from the Gulftown-based chip.

Similarly, HandBrake readily takes advantage of available cores, so again Core i7-3960X snags first place. Everything else falls in behind, generally in the order we’ve come to expect from very well-threaded applications.

The funny thing is that cores don't scale well. They do, but it's far from ideal as the percentages from the 2600K show (and the FX-8150 but that's a different story).
But the takeaway:
-If you're playing games the i5-2500K is the best purchase you can make and it's enough for Tri-580 SLI. Only WoW shows any difference, but most games ignore it.
-X79 is Intel being just plain lazy. No matter how you slice it- the X79 should have been called X67 and left like that. It's also a wildcat platform that will only support at most 6 CPUs that aren't terribly crippled.
-A Phenom II 955BE (or unlocked 960T, or a 1090T/1100T) is still a fine CPU to have unless you're gaming with dual graphics cards or doing time-intensive tasks.
What we have today is simply a platform for bragging rights not a serious contender to the X38, X48, X58 family.
I would LOVE to see them pick up their game and provide me with a worthy upgrade over my 4GHz i7 2600 (Non-K). I would swoop it up.
Look, BD had 4 modules with two "cores" each, each module is equivalent to a Sandy Bridge core.
They should just combine both of those cores or make them a single core, so we get 4 threads.
Then create 4-6-8 core versions of those CPU's..
Think about it.. the FX8150 is more of a 4-core CPU where the resources are halved pretty much so you get two threads per core, it would have been MUCH MUCH better if they just kept 4 strong cores.
Not sure why either but I always seem to start an AMD related comment :\
The labels are wrong on the graphs on this page the last ones should read DDR2-2133 on the last two shouldn't it?

The only use for the 3820 really seems to be a cheap placeholder processor if you need a new PC now, but want to wait for a likely full 8c/16t version to come out around the time Ivy Bridge is released. The 3930k should prove to be a very good high end gaming/ mid range workstation part though for people who invest close to $1k in graphics cards.

Yessir! Working on it now!
Yes. Its expensive. In other news the Earth orbits the Sun. I wish I had enough $$$ that the costs of this CPU was inconsequential to me.
