5.0 out of 5 stars Top Quad Core CPU. 1 May 2012
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. At time of writing (the morning of release), it is marked up 5% above retail and has the wrong list 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.

5.0 out of 5 stars Very Good CPU for Workstation 21 July 2012
Verified Purchase
The Intel i7 3770K is a fantastic processor, I wanted to build a workstation PC for 3D graphics, but I couldn't afford a proper Intel Xeon CPU, so I opted for this instead. I was a little apprehensive about using an i7 instead of a Xeon for professional level work, but so far I have been pleasantly surprised. Admittedly it isn't as fast as a Xeon, it was never going to be, but its not as far off as I had first thought.

I haven't tried overclocking this yet, but it idles at 1600mhz for most tasks, it only every changes when I start animating or modelling in 3D applications. The Intel Turbo Boost feature confuses me slightly, the CPU never seems to run at its described 3.5ghz, always shooting up to its 'Turbo Boost' levels of 3.9ghz, which I thought would have been reserved for only the most intense of operations.

Ultimately, you can't go far wrong with this CPU, unless you work for Pixar and need the most powerful machine known to man, this will be more than good enough for anybody's needs, especially if you don't want to fork out for the i7 extreme or Xeon CPU's.

5.0 out of 5 stars Perfect for Everything I do 27 Mar 2013
Verified Purchase
Please let me start by point out I do some intense gaming and intense video editing as well as he light load stuff like word documents ect for college,

As a computer student, I knew what I was going to need to give me the 'horse power' in all round applications. And the I7 3770K is great for this. Whilst only having 4 physical cores, it can be hyper-threaded into 8 cores. I had previously read that this wasnt as good as an 8 physical cored processor -as your probably have guessed, but I went ahead with my purchase.

Instillation was relatively simple, but I was still neverous at placing the brackets back over - I didint want to damage a pin on a 250 CPU. But everything installed great! Please note, this does require 2x 6 pin power for the PSU.

After instillation I done what any other self confessed geek would do; I jumped straight into my benchmark software. Firstly, I tried the Intel Burn Test -which isn't actually made by intel. This little piece of software seen all 8 threads jump up to 100% load and reached around 68 Degrees Celsius. On a after market Corsair H60 Cooler.

I then used 3D Mark 11 and Vantage, unfortunately I do not have these results to share but the end result wasn't stunning but it was highly respectable.

But I guess it more of a work load based thing. So I opened up my Sony Vegas Pro 12 (64 Bit) and started doing some video editing. The results were brillant! I edit in 1920x1080p full HD and the CPU was utilizing all threads for the work @ around 50-60%. I then rendered the video and the cores reached the expect 60-80% work load and raised to 50 Degrees Celsius. My 10 minute video was done in 7 minutes! I was astonished! I was previously using an AM3 AMD Phenom x4 955 BE and that took up to and hour for a similar piece!

5.0 out of 5 stars Brilliant! 26 Jun 2013
Verified Purchase
There is no need for Haswell the boards are more expensive and as a gamer you will pay more and get a 2% benefit. This CPU is just as good and will be future proofed for next-gen games with hyperthreading. You WILL need 8 threads in the future to run next-gen games at good settings. The 8 threads on this CPU will prevent being CPU limited in games. You must get this over a 3570K or a 4670K.

5.0 out of 5 stars As expected 12 Nov 2013
By Tim S.
Verified Purchase
I’ve chosen 3770K over Intel’s 4th generation processor (Core i7 4770K) as I was concerned with the latter’s oveclocking abilities. 4770K runs much hotter and there is also a big chance it will not go over 4.2GHz. It is also marginally faster at the same clock speed.

The other reason to chose 3770K over the newer one was the slightly lower price for the motherboard and the CPU itself.

I was not disappointed and the processor passed an 8 hour Prime95 stability test at 4.5 GHz and 1,176V. The temperatures were in the upper 60’s C with my SilverArrow cooler which is perfectly acceptable.
