You may need to update your BIOS for your motherboard to recognize this CPU. It is an LGA 2011 socket platform CPU but these are the new Ivy Bridge E 4th generation Core i7 Extreme microprocessors hence a BIOS update may be needed. I had to use the Asus USB BIOS Flasback cause my P9X79 board wouldn't even start into BIOS. The motherboard CPU warning light would turn on when trying to power on so I downloaded the lastest BIOS from Asus website. Renamed the file extension from .ROM to .CAP. Copied it to a Fat formatted USB stick. Stuck it into the motherboard USB port and pressed the flashback button. Waited a few minutes and it was done. There is a video on the Asus website on how to do this. Finally the system booted up right away and then I literally just put the CPU voltage to 1.2 and the multiplier to 44 and it's been running cool at 4.4 GHz every since. It could easily go higher but this is more than enough power for me. I haven't done any formal stability testing yet though, just a few benchmarks but I've been playing BF3 for days now (ultra detail at 100 to 150 fps) and now BF4 and it's been very stable for me. Other specs are ASUS P9X79 board, Intel RTS2011LC Water-Cooling Kit, Kingston 16 GB DDR3 1600mhz ram, PowerColor HD7990 6GB GDDR5 V2, XFX Pro 850 Watt PSU, Kingston SSD 120 GB, and Windows 8.1. In BF4 I'm averaging about 80-120 fps in ultra settings across all maps. In BF4 CPU hits about 70-80% load with temps hovering around 48c. Idle temps are about 30c.
Update 11/3/2013:
I just increased my overclock by a little bit more. This time I set the CPU voltage to 1.225 v. BLCK frequency was set to 100 Mhz. Multiplier was set to 45 giving me an overclock of 4.5 GHz. Memory settings and timings were the same as before, 9-9-9-27 at 1600 Mhz. I ran a 4 hour Prime95 blend test and it passed all tests. CPU temperature range during the 4 hour test at 100% load was a minimum 48c to a maximum 53c. It stayed mostly between the 48c to 50c range throughout the test however. Idle temp right now is 31c.
Update 11/14/2013
With the recent BF4 update I'm averaging a much higher fps with 100-150 fps on ultra settings and still overclocked at 4.5 GHz. **Other things to consider: Intel will be releasing their new Haswell-E 6 and 8 core CPUs in the 2nd half of 2014. It will run on a new X99 chipset with support for the new upcoming DDR4 ram. DDR4 ram however won't be released to the consumer desktop segment until 2015 supposedly. Can you wait for about a year to upgrade to one of these new Haswell-E CPU's and stick with your current system for now or do you badly need to upgrade right now? This is an important question to consider. For me I'm pleased with my upgrade and the value and cost I got for it. We'll have to see what the pricing will be on these new 6 and 8 core CPUs but the previous Intel 6 core CPU offerings have been prohibitively expensive for quite some time at least for the mainstream to enthusiast gamers.

Well were to start I've been building AMD machines because the price to performance ratio is very high. This is my first Intel build and I'm very impressed. I did allot of research on the both the 4770K and the 4820K and decided on the 4820K for it's better crossfire/sli support, in order to get 2 full length pci-e X16 slots. These can be had on z87 boards but it can be much more expensive, my X79 board of choice is a GA-X79-UD3, I ended up paying $199 for it and it is pretty good, the board had a sketchy beginning but the new rev1.1 is great and compliments the 4820K very well. Now for the reason I got the 4820K over the 4770K, the 4820K is the better overclocker, it uses solder on the IHCS rather than thermal paste, AND the voltage control since its ivy-bridge remains on the motherboard where it belongs. The 4770K beats the 4820K at stock speeds but when overclocked it performs way better and since the cpu runs so cool my hyper 212 evo can keep this thing at 45*C at full load and withstand 8hrs of prime95 "blend" test at 4.3GHz and not even come up with an error. Sure you can overclock the 4770K but you are going to see temps exceeding 60*C even on water cooling and though they just run at those temps normally I still don't like them. The 4820K is rock solid even though it was $320 I feel as if it were money well spent. Most would say its overkill for a gaming build but since I have the innate ability to multitask the crap out of a computer with a primary/auxiliary monitor I feel I could make very good use of it. All in all the total up grade came out to around $525, am I happy with it? OHH Yess........

First thing is this a huge processor. packing is small and that is because it does not come with a cooler. You have to buy a cooler separately but Intel offers a cooler which I listed below.
Install was easy and the processor was heavier than any other bare processor I have seen. Best of all this processor is super fast, installing windows 7 took almost half the amount of time on a SSHD.
