***Update 06/03/2013: The next generation Haswell i7-4770K and i5-4670K have superseded the IvyBridge i7-3770K and i5-3570K. They are between 0-15% faster in most regards, depending on task. See AnandTech's "The Haswell Review" for details.

As of 04/29/2012, this is the current top-end "premium" tier Intel chip - about 5-10% faster than the i7-2700K which it replaces. The current top-end "extreme" tier is and will remain the six core i7-3960X until the second half of 2013, when the Ivy Bridge-E is released.

It overclocks nearly as high as Sandy Bridge and heats up more with voltage. This means 4.4 to 4.7 GHz will be around the limit on air. Note that if you do not plan to overclock and/or intend to run virtual machines, the plain 3770 is the cheaper and better choice as it has Intel SIPP, vPro, VT-d and TXT enabled (the K has these disabled).

At its official retail price, three hundred and thirty two dollars, it is currently one of the best values for a high performance chip in the market. The next steps up are 2-3 times this price.

The GPU performance compared to the 2700K is about 50% faster, which is equivalent to a $40-60 video card.

CPU: Ivy Bridge i7-3770k
MB: Asus Maximus V Gene
GPU: EVGA GeForce GTX 680(OC'd to 1286Mhz core clock & 3400Mhz memory clock. AC Twin Turbo II heat sink installed)
MEM: 16GB Mushkin Enhanced Redline 2133Mhz(OC'd to 2400Mhz)
SDD: 2x 240GB Mushkin Chronos Deluxe in RAID0
PS: Seasonic 1000W 80+ Platinum
CASE: Fractal Design Define Mini

As we all know, Ivy Bridge runs pretty hot overclocked when compared to its predecessor Sandy Bridge. Arguments have been made as to the reason of this and it may be due to its newly implemented 3D transistors or because it uses thermal paste as a conduit between the heat shield and the CPU die or maybe its due to a combination of both. Regardless, IF you plan to overclock this sucker YOU WILL NEED A 3RD PARTY COOLER!!! Whether it be water cooled or air cooled or even cooled by ln2, do your research and find a good heat sink!

Most reviewers are reporting that you can reach a decent overclock of 4.6Ghz at around 1.275 - 1.300 volts with temperatures reaching the 85-90C mark during stress tests. This is considered NORMAL because Ivy Bridge is more resilient to high temperatures than Sandy Bridge. To be safe and to lessen CPU degradation, aim for no more than 1.5v and MAX load temps ~90C. For the majority of people out there, this type of overclock should suffice.

Currently I am running my CPU at 4.6Ghz at 1.300v for the extra headroom.

Verified Purchase
The i7-3770k is a fantastic processor! Out of the box (with no overclocking), I got a Windows Experience Index rating of 7.7 (on a 1.0 to 7.9 scale). The CPU installation is quite easy and the 'k' at the end of 3770k means the processor is unlocked for easier overclocking. The HD 4000 graphics are also great! I got a Windows Experience Index of 6.5 in both graphics categories without the need for a discrete GPU (if you don't need serious graphics performance, this processor could save you money on a graphics card!).

This chip laughs at anything I give it. It can transcode a 1 hour 45 minute HD video in just a few minutes without using most of the full force of the processor (my particular trial lasted about 11 minutes and utilized just under 20% of the CPU power including my internet browser).

I do have a few light reservations, however. First, the price is going up (at least on amazon) and will eventually drop off a bit. The recommended retail price (given by Intel) is around 320-330 (similar to what the i7-2700k goes for).

Second, the Intel Core i5 3570K Processor 3.4 4 BX80637I53570K shares a lot of the great features of the i7-3770k for a lot less money (100 dollars or more cheaper). You lose 2MB of L3 cache, 100 MHz in clock speed and turbo speed, and the hyper-threading technology when you move down to the i5-3570k. But you keep the HD 4000 graphics and the unlocked processor for overclocking (the i5-3570k might even be slightly better for overclocking purposes which could make up for its 100 MHz decrease, and even some of the hyper-threading).
