I just put together these parts:
GIGABYTE GA-Z77-D3H
i7-3770S
16GB RAM
256GB SSD
Needless to say this thing is very fast. 7.8 processor and memory score, 7.9 hard disk score. It took less than an hour to install windows, the gigabyte driver disk, and fully update it.
I moved one slider in the bios and it runs pretty much constantly at 3.94 GHz, unless idle. It is supposed to be 4.02GHz but I never saw that. Even with 8 threads of prime95 it is supposedly running at 3.94GHz.
Temperature under 8 thread prime95 load is 95C, after 10 minutes. Who knows where it would top out...
Super pi 1M time is 9.34 seconds.
With 6 prime 95 worker threads set to cores 0-5, and super-pi set to core 6-7, super pi time drops to 10.99 seconds.
Both times are very consistent. I repeated this test several times.
I assume there is some throttling going on though it is nothing too terrible. CPU-Z still insists it is running at 3.94GHz.
Now here is where it gets interesting imo.
In addition to the previous test I added Furmark into the mess. So I had the following test configuration:
Furmark 800x600, no MSAA, windowed mode. Burn-in running, affinity set to cores 0-5
Prime 95 6 worker threads running, large FFT, affinity set to cores 0-5
Super-pi set to cores 6-7
I set everything else (dwm, explorer, etc) to cores 0-5
Aero enabled
And with that test configuration, super pi 1M time drops to 17 seconds. Very repeatable. Temperature is around 85-88C when running these tests.
The system is very unresponsive when furmark is running. It feels like an atom netbook even when you're just browsing sites like MSN. Even with no cpu load at all.
This HD4000 gpu runs furmark 800x600 windowed at 12 fps, which is 3 times faster than the Nvidia 9xxx series discrete gpu I have in my other machine. Yet my other machine does not slow down this badly when furmark is running. Furmark running has virtually no effect on my general usage experience on my machine that has the discrete gpu. But on these integrated graphics systems, the effect is horrific. I noticed the same thing on my llano system. If you load the gpu it inexplicably slows down the whole system to a crawl. This does not happen the same way with discrete cards, even a supposedly far less capable discrete card! To my knowledge, not one tech review site has revealed this problem. And it definitely is a problem.
I would very much like to see someone with a properly cooled i7-3xxx set their cpu to 4.0GHz and repeat the super pi test in the above test configuration.

But even so it is priced fairly. It is the cheapest way to get 8 threads and a super pi time of 9 seconds. A 2600 is $20 less (~7%) but the IPC is 7% less too. K version pointless because of stock cooling.
