I'm constantly using my computer, be it gaming, Mixing, editing videos or general use and for all of that i require a fast CPU. I was making do on a cheap AMD Phenom II 965BE, around £100 to £90, personally it was a great little CPU for the price and i would also recommend that to anyone looking for a great gaming CPU. However i also record gameplay on my PC so i require i beefy CPU, then i have to render out many 1080p video files and for this reason i opted for an i7 over an i5 thanks to the hyper-threading that helps with overall multi-tasking but also the quality of my recording. I have seen a healthy increase in performance overall in all areas over my old CPU, this CPU is triple or near enough triple the price so that's something i expected non the less.

You can see the quality of this CPU on my YouTube Channel DeanGetYourWings.

This or a 2nd Generation:

If you are thinking of upgrading from a i5-2500k or i7-2600K i would personally not recommend it, you'd not get a huge amount of power increase (i believe its 25% over a i7-2700K per clock) so it has the edge but its hard to justify the price for a small gap, if you however like me were upgrading from an old CPU or outdated CPU and you had a reason to require the hyper-threading capabilities then i recommend grabbing a Ivy Bridge CPU and a good mid-range heat sink to combat the extra heat created by the lower nm technology.

Heat!:

Its well know the Ivy's run hotter and dont clock quite as high. I got the CPU before my cooler arrived and had to try it out using the very, hateful Intel stock cooler. Temps would be 34c to 85c at max.

(Former) Top quad core CPU 29 April 2012
By nako - Published on Amazon.com
***Update 06/03/2013: The next generation Haswell i7-4770K and i5-4670K have superseded the IvyBridge i7-3770K and i5-3570K.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. This is enough to play most games at mediocre quality with a mediocre framerate or run Quick Sync very fast (Intel's custom medium-quality h264 encoder; about 300 frames per second on 1080p video).

If you do not have much use for the GPU, most i5 and i7 owners will have a hard time justifying the Ivy Bridge upgrade. All other slower chips will see a substantial improvement. Another good value is the Ivy i5 3570K which is something like 0-15% slower and 30% cheaper.

The new motherboard lineup consists of the Z77, Z75, H77, Q77, Q75 and B75 chipsets. The major improvements over the Sandy Bridge generation is native USB 3.0 support, PCIe 3.0 (with Ivy chips only) and SSD-HDD hybrid caching. Z/H/X all have CPU overclocking. The 77s have the SSD caching. Most owners of this chip will probably get a Z77 which is feature rich and nearly the same price (about ninety dollars for the cheapest board currently).

Awesome CPU!!! Don't be scared of higher OC temps!!! 1 May 2012
By lawpnoy1 - Published on Amazon.com
-SETUP-
CPU: Ivy Bridge i7-3770k
HEATSINK: Noctua NH-D14
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

-OVERCLOCKING-
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.

-RESULTS-
Currently I am running my CPU at 4.6Ghz at 1.300v for the extra headroom. Here are the temperature results during stress tests:

NH-D14 in "normal mode"(~1300RPM)
Intel Burn Test: 85-92C
Lynx: 80-85C
AIDA64: 70-75C
Prime95: 75-80C

NH-D14 in "silent mode"(~900RPM)
Intel Burn Test: 90-95C
Lynx: 85-90C
AIDA64: 75-80C
Prime95: 80-85C

The temperatures were about 4-5 degrees cooler in normal mode.

-CONCLUSION-
In the end, this processor proves to be a true successor to Sandy Bridge due to its performance increase and lower power consumption; however, these performance increases are marginal at best. This means that if you're thinking about upgrading coming from a 2600k or 2700k, don't bother. Unless you absolutely need to have the latest hardware or if you want features such as integrated PCI-E 3.0, USB 3.0, higher memory bandwidth, HD 4000 graphics, etc... keep your Sandy Bridge. IMO, you shouldn't upgrade your CPU unless you're at LEAST 2 generations behind. I upgraded coming from a Yorkfield Q9550 and am very happy with the noticeable performance boost. Though temperatures are higher than what we're used to seeing, it doesn't mean that it's a bad thing, it's just different. So don't let high OC temps shy you away from this great piece of hardware. Great product Intel!!! A++

-UPDATES-
04/29/2012
- Bought the product

05/02/2012
- Managed to get it stable at 1.280 volts at same 4.6Ghz. New temps are all 5C cooler!!!

05/17/2012(FINAL)
- Reduced to 1.21 volts at same 4.6Ghz.
- Highest load temp was 85C while fans were in silent mode.
- Reduced memory clock to stock speed(2133 Mhz), and timings(9-11-10-28) to run prime95 for ~16hrs. Overclocked them back to 2400Mhz 10-12-11-32 after stress testing since they run just fine. No BSODS or random crashes. If I do experience any issues with stability, then I know I need to clock the memory back down, otherwise I'll keep the extra speed.
- No updates shall be added unless something drastic occurs.
- Remember, running stress tests on a new PC is done only to test stability. In a realistic environment, you will not be running your machine at 100% load 24/7 unless you're folding proteins or something. On a normal day of playing games, surfing the internet, listening to music, watching moves, etc... my CPU does not go above 70C and averages around ~60C.

Excellent (with Light Reservations) 9 May 2012
By Quinn G. - Published on Amazon.com
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). In general, if you have software which can fully utilize 8 threads, this processor is probably worth the extra cost.

Third, the ivy bridge lineup does run a bit hotter than sandy bridge, but this is completely expected from a smaller architecture. This shouldn't be much of a problem (very good overclocking with air is still easily possible and extreme cooling allows for some incredible results) but upgrading from an overclocked sandy bridge might not make much sense - unless the HD 4000 graphics are worth it for you.

Overall, this is one of the greatest processors available today (definitely the best performer on its socket type). Any processor which beats this one costs at least several hundred dollars more and doesn't gain nearly that much in extra performance. So, if you can handle the somewhat higher price than the i5-3570k, get this beast of a CPU!

Temperature prime95 x64 maximumheat on watercooling 3.9GHz (default setup) 7 Aug 2012
By Marcus - Published on Amazon.com
Verified Purchase
Water Cooling (2 Liter selfmade custom radiator)
100% CPU load on maximum heat stress test prime95 x64 @3900MHz.

Room temp: 25°C
Mainboard temp: 30°C
CPU all cores: ~68°C
CPU mainboard: 55°C
IDLE @1600MHz all cores: 37°C
IDLE @1600MHz CPU mainboard: 34°C

Intels CPU Tcase: ~67°C (which should roughly be ~10°C lower than core temp - theoretically
measured on top of the cpu heat spreader, but there is no sensor)

The Tcase temp is the maximum temp intel guarantees it to work perfectly fine. So adding ~10°C to the core temps you measure, the allowed maximum should be around ~77°C for not overclocked systems. I reached this in stress test with watercooling, while the water and copper pipes I use just are lukewarm.

The problem is the high density of the CPU under it's new hood. It's more cramped together and less coolersize to give it up to. So it's only normal to be more hot than the older generation.

The new HD4000 integrated graphic chip, which shares place with the 4 CPU cores is taking quite the huge part and if you are not careful in selecting your mainboard, you will find this GPU completely unused by your system. For the information: Intel is not working in harmony with Nvidia so you can't combine the GPU of Intel and Nvidia (normally). I got lucky with an ASUS mainboard, which uses Virtu Logix that is at least able to switch on *exe, which GPU shall be used. That means both are using their minimum power all the time, which is more as if you just run your PC with only the CPU HD4000 graphic. But therefor you can have the ultimate power more easily. For example is nvidia with CUDA much slower than Intel in converting HD videos now, with the right Software (Media Espresso). Took me 2 Minutes to convert a 1.4GB 1920X1080 video stream with HD4000, compared to 4 Minutes with CUDA on a GTX560TI from NVIDIA. So this onboard Graphic can be very supportive with the right applications and may save energy for older programs that don't need a 300Watt power consuming PCI-E video card. :)

Overclocking:

As others mentioned in various tests and benchmark, it might only take 1 minute to overclock this CPU, even in windows easily and stable. On my first day I just tried to see and made 4.5GHz stable with just rising the voltage to ~1.2V Be careful with your mainboards OC abilitys. Mine took advantage while it had some "auto range" and pushed this cpu to 1.45 Volts already while I didn't notice. I only was warned by mainboard CPU sensor peak temperatures of 75-95°C for short. This was probably the mainboard sensor only. Means the core was probably even more hot. So the tendency of this thing is to heat up fast if it gets too much voltage. I used to set 1.85V later and the autoranger software pushed it up to 1.25V. The trick is to get as low as possible and have it still stable calculating. The less heat you will receive. So 1.2V might be a working number, but depending on your software/bios and mainboard this may vary.
Sum: While running on 4.5GHz or similar this thing beats up the 1st places on some CPU benchmarks in AIDA64 or Passmark. For more power I had to update Win7 to SP1 since 1 CPU feature was not used before. The Benchmark AIDA64 advised this and the result prooved the higher power with SP1.
Ah, btw: the cores are clockable individually or together (4 cores in total). So you can have core 1 on 3400, core 2 on 3900, core3 on 4300, core 4 on 3600MHz. I don't really get an Idea how to use that feature yet, but it might save power or if you are using software that adresses individual cores only, you might save heat if you have the unused cores throttled down at slow speed. Who knows yet?!

With this CPU you will have one of the most powerful CPUS there are at the moment. Only contrary is the integrated graphic chip that I did not need. If you go for a Z77 chipset you can use the full overclocking potential and can use the integrated graphic, as well as a dedicated one. Depending on the MB manufacturer maybe the Virtu MVP to switch between both in windows.

I would have bought the same CPU withouth the HD4000 since I don't render videos or playing in low resolution. The software that uses quicksync to squeeze out the full power is very limited at the time. Mediaespresso for example, and this can not render MKV HD audio files, which makes it totally useless for me. What does the speed if the file format I want is not supported? :) It makes me feel strong, but useless too. Thanks to not having the integrated graphics on the mainboard and in the CPU instead it only wastes important cooling space in my opinion and therefor overclocking power is limited due to higher temperatures, thanks to a iGPU that overclockers don't really need to have for gaming.

Hope this was helpful

Another winner from Intel! 28 May 2013
By MOAR COARS - Published on Amazon.com
I have had this CPU since it first came out so I decided to write a little review about it. The 3770K is ~10% faster than the 2600K but runs much hotter and that's because of the TIM that Intel decided to use. Many people who are overclockers recommend delidding the CPU to reduce the temp. I have personally delidded mine and it reduced the temp greatly, ~8-9c less under load. If you plan on overclocking this beast then prepare to spend some money on a quality air cooler or water cooler. The stock cooler is a joke if you plan on overclocking it. Even the Hyper 212+ is a thousand times better at cooling the CPU.

Most of the people on the forums have no trouble reaching 4.5Ghz and doesn't require much voltage. I'm using a Corsair H100i to cool my CPU which is overclocked to 4.8Ghz using only 1.38 volts. Since I have delidded it, it runs much cooler than it used to when I got it and the temp doesn't go above 80c. I would personally try to keep the temps under 80c regardless of what overclocking you are trying to get out of the CPU. Ivy Pride handles high temps a lot better than Sandy Bridge but it may degrade the CPU faster.

I use my PC to play modern games such as BF3, FC3, Crysis 3, Bioshock Infinite and Metro Last Light and this CPU has absolutely no issues at maxing each game. I noticed huge improvements in FPS when I overclocked the CPU to 4.8Ghz from stock in BF3 MP. The game would run a lot smoother and the min fps increased tremendously. If you are into serious gaming then this CPU will eat anything you throw at it.

AMD really needs to step up their game and release a new CPU to compete with Intel because their FX-8350 is slow in single thread performance. The majority of the programs and games are more dependent on single core performance than multi core performance and that's where AMD is struggling. I recently got a GTX780 and it works beautifully with my 3770K at 4.8Ghz. I was going to upgrade to Haswell but it seems like it won't be necessary because it's less than ~5% faster than a 3770K.

My full rig:

Case: Corsair 650D
GPU: EVGA GTX 780
CPU: Intel Core i7 3770K @ 4.8 GHz
PSU: Corsair AX850
Ram: Kingston 16GB of RAM
SSD: Samsung 840 Pro 256GB
MB: ASUS Sabertooth Z77
OS: Windows 7 64bit
