Once again Intel sets the pace in competition for performance and power efficiency with the 3rd Generation Intel Core processors, codenamed Ivy Bridge. Built on the market-leading previous generation Sandy Bridge architecture, the state-of-the-art Ivy Bridge not only continues the excellence in all aspects with Intel Hyper-Threading technology, Turbo Boost Technology 2.0 and Smart Cache, but pushes the pace a step farther with groundbreaking 22nm 3D transistor technology, which delivers an unprecedented combination of performance and power efficiency, and a couple of key refinement. The built-in visual is another leap offering you enhanced media and graphics. The Ivy Bridge IGP also supports DirectX 11 and OpenCL 1.1 to deliver incredibly detailed gaming and better heterogeneous computing performance.

The Intel Core i7-3770K packs four cores with Hyper-Threading technology and Turbo Boost 2.0 technology to deliver top-of-the-line performance that makes a difference you can see and feel in HD or 3D, multitasking or multimedia. Its unlocked multiplier allows you to freely adjust the frequency when used with compatible motherboard, pushing the performance to a new level and pumping the max out of your investment.

Nearly 7 years later....STILL great! 6/14/2019 11:55:56 AM

Pros: Reliable, Fast, Bang for my buck value....LONGEVITY!

Cons: Absolutely nothing

Overall Review: I bought this in October 2012 and recently I was looking at upgrading to an SSD. Before doing so I pondered building a new machine that is until I checked Tom's HW CPU chart and was astonished to find this so highly rated STILL! I opted to upgrade the HD to SSD and from my 660ti to the 1660ti GPU and I can not be happier. So glad a friend recommended Ivy Bridge because this CPU has been nothing short of fantastic. Now that I've completed the SSD upgrade it flies! Could not be happier!

Zero regrets buying a Core i7-3770k for a gaming rig. Worth every Penny 3/17/2019 10:28:02 AM

Pros: This was for my brothers gaming rig that I built him in September 2012. Right now this CPU does very well with the GTX 1070 he upgraded to . I knew that down the road, buying the Core i7 would pay off. After 5 years it's kinda hard to believe how the 3770k has retained it's value and how much the 3570k hasn't. Even for modern gaming this CPU does great if it's paired with the right graphics card.

If you're gaming at 4k you could easily overclock this thing to 4.2ghz then pair it with a GTX 1080ti and game on without worry. At 4k even the best graphics cards are bottlenecked but you still need a capable CPU. The 3770k will meet your gaming needs if your FPS target is 60fps-90fps, depending on the game. The only time you should consider the Core i5-8600k or the Core i7-8700k is if you're going to use a 144hz monitor and you need that extra push from the CPU to boost FPS. You start to notice the benefits of having the fastest CPU when your FPS are at 90fps.

This is the best CPU you can buy for the Socket 1155 platform, unless you count the likes of the Xeon E3-1270 v2, E3-1280 v2, E3-1285 v2, or E3-1290 v2 which are locked. However, if you have an h61, h67, b75, or any other non-Z or non-P67 motherboard then you can look at the Core i7-3770 which is cheaper than the K version or a Xeon E3 v2 CPU.

*EDIT 03-17-19*
I bought a used 3770k that can do 4.8ghz at 1.35v (1.36v according to CPU-Z)..... and this is a Golden Sample. I don't think the guy who sold it to me knew the chip he has was within the top 1% otherwise he could have sold it for more. So far this has passed 5 hours of Prime95 v.29.6 Small FFT's and 15 rounds of LinpackExtreme 10gb test. I delidded the 3770k before I even tried to overclock and I have this 3770k on a custom loop with a GTR 360 and an EK Supremacy EVO block and the max CPU temps haven't exceeded 71c.

Cons: The cheap TIM keeps this from being a great overclocker. As far as Silicon and architectural quality goes, the 3rd gen processors typically don't overclock as well as Sandy Bridge processors

I own a 2600k that can easily hit 4.8ghz at 1.35v and it's stable as a rock. With the old Corsair H70 the temps never hit above 73c while running IBT. 71c-72c running Prime95.

This 3770k I bought from newegg easily hist 4.6ghz at 1.31v (offset) but the old H80 it was paired with could not keep it from hitting 90c while running Prime95 Blend. The board I bought was an Asus z77 Sabertooth. Other than that one shot of overclocking to see how well the 3770k rates in the Silicon Lottery world, it's been running at stock speed since Sept of 2012.

I also have a Core i7-3770 on a P8P67 WS Revolution motherboard and the max the multiplier will go to is 43. I increased the Baseclock to 103 and I got the chip to 4.4ghz and it passes all stress tests. Keep in mind that some boards will flip out if you touch the Baseclock, and you really can move the Baseclock past 105 because it's tied to the PCI-E lanes. If you are looking to upgrade and you aren't going to overclock very high then you can look at the straight i7-3770 or a Xeon E3 v2.

Overall Review: I have no regrets buying the Core i7 and pairing it with a GTX 660ti over the Core i5 and a GTX 670/680. Back then games sometimes took a 1% hit by trying to use the Hyperthreading and it made zero sense to buy an i7 for a gaming rig.
Now you have games like Overwatch that greatly benefit from the H/T. Also, the 3570k is at the point where it is almost bare minimum for gaming because games in 2018 are using 6-8 threads. I know a couple people who have recently upgraded their 3570k to the 3770k because they need something that can take on more threads.

In the end I'm happy I paid more for the 3770k. If you plan to keep your system for the long run and you have the extra $100 to spend then get the i7.

Overclockers Delight. 12/10/2018 10:36:20 AM

Pros: Update: 6 years in. 4.8 didn't hold up but 4.2 has been running for more than 5 years without so much as a hiccup. I've replaced Ram, Upgraded to a 1070 and game at 1080p with ridiculous FPS while encoding on slow for my stream.

Overclock stability at low voltage.
Generous l3 cache.
Matches more expensive i7 3930k with only a slight overclock. Surpasses it with a little tweaking.

Cons: Can't really think of one.

Overall Review: There are tons of articles on the net about how Ivy bridge doesn't over clock or doesn't stand up to sandy bridge in terms of this or compared to that. All of these assume you are buying some $30 cooler.

If you are spending $300+ on the CPU why would you use a $30 cooler. I am using the Noctua NH D14 currently at 1.3v and 4.8ghz stable. Never getting above 70C at full load.
