4 out of 5 eggsHyperthreading

Pros: Fast, ease of use and overclocking.Great for gaming and good for productivity.

Cons: The one i received only overclocked to 4.4ghz, I was hoping for at least 4.5 stable. On water-cooling.

5 out of 5 eggsExcellent upgrade processor

Pros: Want more power without spending a lot of money! Take your existing Sandy Bridge core i3 or core i5 setup, remove the processor. Update the bios on the existing LGA 1155 board (I learned how to do it from a youtube video), pop in this new processor and you will see an instant difference. I noticed instantly that downloads were faster, less buffering and smoother streaming and my favorite games, Flight Simulator X could have the frame rates raised.

Cons: I know many folks buy this processor to overclock it. I did that once it was installed. However, my favorite game would crash unexpectedly. After updating the drivers for the video card and re-installing the game (none of which solved the problem), in desperation I cancelled the overclocking. My game has performed smoothly ever since. So the con is, overclocking may cause more problems than it is worth.

Other Thoughts: Computer are expensive, just upgrade the processor with this sweet Ivy Bridge core i 7-3770k and save some money.

5 out of 5 eggsBetter than expected

Pros: It's a powerful quad-core CPU with multi-threading and an unlocked multiplier, the best you can get for the LGA-1155 socket. Works great on my Asus Z68 motherboard after a BIOS update. Incredibly fast in every task even at default clock speed with a reasonable TPD. And unlike the Sandy Bridge equivalents it uses PCI Express 3.0, so I won't have to upgrade my CPU for 5-6 years.

Cons: It doesn't cook breakfast for me.

Other Thoughts: I got this as an upgrade from my i5-2500. I didn't know as much as I do now about computers and I quickly regretted not getting the i5-2500K or i7-2600K along with my Z68 motherboard. So I saved money to get the best of the best: PCIe 3.0, hyper-threading and an unlocked multiplier seemed worth upgrading.

But the best wasn't written on the spec list. I heard about Ivy Bridge's poor overclocking performance, people with a similar setup as mine generally aren't able to go higher than 4.3-4.4 GHz. But I was able to reach 4.8 GHz! And it's 24h-Prime95 stable, I could probably push it even more but I don't want to needlessly stress such an incredible chip. I guess I won the silicon lottery and I'm really happy about it. Of course it won't apply to everyone, so I can't write that in the pro field. If you're an overclocking enthusiast you might want to look at the i7-4790K with improved thermal interface on the latest Z97 platform. But if you have a weaker i3 or i5 on a P68/Z68/Z75/Z77 motherboard and want to future-proof your system, get this while it's still available.

5 out of 5 eggsAmazing

Pros: Easy to overclock with the correct motherboard. Seamless transition, and hyper threading.

Cons: Random cases of cpu lock up and cpu usage will boost to 99%. This is a rare defect and normally does not happen.

5 out of 5 eggsI am impressed

Pros: 1. My cpu must have been cherry picked. 5.0ghz @1.53v on 140xl nepton aio @100c in prime 95 small fft, but never goes past 90°c in 3d mark tests.... LOL

2. I run this cpu at 4.5ghz @ 1.22v for a nice 65°c prime small fft max temp

3. Igfx hd4000 is at 1400mhz +200mv @4.5ghz 65c

4. Igfx is at 1600 +200mv (max voltage on motherboard) @ 3.5ghz 40c

5. After applying better thermal compound my temps dropped 15c at 5ghz (not a huge change)

Cons: My first cpu received was faulty. 78°c at stock clocks, i needed 1.35v for it to be stable. Did not test the Igfx.

The cooler supplied for a i7 unlocked overclocking chip is....I've deleted so many versions of this sentence

Other Thoughts: My rma with newegg went quickly and smoothly less than 1 week to have a new cherry picked chip I'm my hands. I bought a 50buck celeron to get me by before shipping it out. Score!

I broke 3 $300 video cards trying to put a water cooler on them. 2 x 560ti and one r9 290.......That's how i learned about the Igfx......

Im running this chip on a z77-hd3 with aftermarket heatsink s on the VRM section, I am also using Ripjaws 1600 At 1800mhz, and a Roswell 750 watt power supply :-)

5 out of 5 eggsVery pleased! Best CPU I've owned

Pros: Very fast computational speed. Cool running (despite the tendancy at 22Nm to heat up quickly) when paired with a quality air cooler. Overclocks easily (mine is at 4.1Ghz fulltime at 1.22volts. Unlocks PCIe 3.0 on my Z69 Fatal1ty motherboard.

Cons: Can heat up quickly, so buy a QUALITY air cooler, or do liquid cooling.

Other Thoughts: I had my i7-2600k for about a year and a half in a z68 Fatal1ty, and bough this 8 months ago. Never installed because I'd heard it can overheat, and that it was more of a sidegrade than an upgrade. Finally installed, and haven't looked back! It is faster in all computations and photo rendering, and has pumped a few extra frames into my GTX 780, either because of it's enhanced cpu abilities, or because it enable PCIe 3.0 on the motherboard. Either way, it actually IS an upgrade.

5 out of 5 eggsOverlocks very well and runs great

Pros: Stock speed plenty fast, K-series so it has unlocked multiplier for easy OC, LGA 1155 platform which has become well established, most binned chips can reach in excess of 4GHz and above

Cons: Cheap TIM, necessitates de-lidding just to get the best temps possible

Other Thoughts: This follow-up to the Sandy Bridge i7 2600K and 2700K is well worth it, it sells for the same price while giving a 10% performance improvement clock-for-clock. It' not much of an improvement when compared to Nehalem to Sandy Bridge jump but it's pretty much a free upgrade for those people who held out, they could easily charge more for this silicon but they don't, improvements are only modest because because of the lack of competition (tsk tsk AMD). It can also utilize faster memory a lot better with the improved memory controller compared to Sandy Bridge so if you have 2000MHz+ memory, it might be better to go IVB.

That being said there are some downsides to this compared to the Sandy Bridge series. More towards the whole IVB line rather than this specific model but cheaper TIM makes de-lidding something people have to do now to get optimal temps, also runs a tiny bit hotter than SB at similar clock speeds. But otherwise it also runs faster so it kind of makes up for it.

Also if you don't do a lot of video editing or such and just plan on using it for gaming, I would recommend you check out the i5 3570K Ivy Bridge or the newer Haswell 4670K/4690K variant. Both have less cache than the i7 line and no HyperThreading function but otherwise they are essentially the same chip for $100+ less. If you don't need HT (a lot of people don't, even a lot of i7 power users disable it cause it causes conflict with some apps and benchmark apps) I recommend going the i5 route, much more economical and makes a lot more sense (plus you can put the money saved towards a better GPU). Only bought this cause I had the extra money and for bragging rights ;)

Overall recommend it, two thumbs up!

2 out of 5 eggshot hot hot

Pros: Much more performance than my i5 2500k.
Raised my average fps
Micro shutter and game hickups are now gone

Cons: Runs 40°c idle with a Coolermaster Nepton 140 XL and 85°c in Prime95 at stock speeds

I was able to achieve a 4.1ghz oc at 1.28v at 92°c

Poor chip.

Other Thoughts: I was able to get my i5 2500 K up to 4.9 gigahertz never went above 60 degrees in my current cooling setup.

when I stop prime95 with this processor from 92 degrees Celsius it's falls all the way to 40 degrees Celsius instantaneously.

I am currently undergoing an RMA process for this processor. I will update my review afterwards. Shame on you Intel. shame on you.
