Intel Core i7-2600K Processor 3.4GHz LGA 1155 95W Quad-Core Desktop

Comment:
Fastest Sandy Bridge CPU out there. Is it worth the extra hundred dollars over the i5 2500K? Depends on the user. For me, it's been great and can easily hit 4.6GHz if not higher (still testing).

I went from a AMD barton 2500+ to this. WOW is all i got to say. Much needed upgrade, really liking this cpu so far. Should be good for the next little while, probably over kill for my needs but hey i don't upgrade every few months so figured i would spoil myself and glad i did....Great cpu.

It's been a short time that I've had this CPU, but I've tried to throw everything I have at it over the past few days after it's initial setup, and it will not quit. It runs at 58-66 Degree's Celcius with a full 100% load at 5.0 Ghz and a cool 29-32 Degrees Celcius when mostly Idle. (Speedstepping disabled) I'm very happy with my choice to purchase this CPU in combo with my Asus Sabertooth.

I upgraded to this from a single core 1.86Ghz Pentium M. Needless to say, this is so much of an improvement that I'm having a hard time maxing out the processor. I can't wait to do some video editing or something and really give it a workout.The processor runs relatively cool: 24.5C at idle and 65.5C under load, with an additional rear exhaust fan on the case. However, I've heard that third-party cooling devices can drop  the load temperature by 10 degrees or more.

The new Sandy Bridge CPUS are simply amazing; not only is this CPU unbelievably fast, the windows experience rating gives it a 7.9 (the highest possible atm). However, this is a rather expensive product.

I went from an Athlon 64 5200+ to this, obviously a huge upgrade for me, with the performance to match. Very fast, cool running chip that's very easy to overclock, I've got it running at 4GHz on the stock cooler at 1.190V and my temps just hit 70°C. Not too bad, but will be much better once I get my hands on an aftermarket cooler.Definitely recommended!

I've been using this baby for a month now and i'm really happy with my purchase. The processor is really fast and powerfull. I've overclocked it to 4.2GHZ and I plan to overclock it to 4.7GHZ as soon as I change the default fan that comes with it. Really good product overall.

Comment:
I bought this to replace an i5 760.Totally worth it.I got an ASUS P8P67 deluxe motherboard and used the OC tuner in the bios to automatically overclock my cpu. It OCed to 4.5 according to CPUID and I am not having any problems... except with cooling.

If your looking to buy a high end computer this processor fits the bill perfectly for you then.

Coming from a q9550 running at 3.4ghz. It did SuperPi to 1M in 14 seconds. This one, at stock 3.4ghz did it in 10 seconds. Going to 4.5ghz does it in 8 seconds.Running it on a Gigabyte P67A-UD5-B3 and cooled with a Noctua NH-U12P se2. With 2 fans on low-voltage power cables.With the low-noise voltage reducers in the Noctua, I'm right now stressing the cores at 4.5ghz, automatic voltage of 1.35v, and the highest it has gone is to 70c on 3 of the 4 cores. Using the Noctua thermal paste. Stable, thus far.Pretty impressed, considering I haven't even touched the vcore, unsettled thermal paste, and not having my cooler fans running at max speed.I'll likely try to push it further after the thermal paste bakes in a bit, and whenever i get around to opening my case again.THough now, I'm not sure if it was worth the extra cash to get the 2600k with the Hyper-Threading. It can apparently be detrimental to gaming performance, but it should come in handy when I'm re-encoding videos or Blu-Rays.I am glad i hopped on the 32nm i7 train after the fudged 1155 motherboard debacle.

This CPU is very great. I have 2 of them. Very easy to OC. Temp are very cool when cooling with a Noctua DH14.Everyone know that intel heatsink isn't great.I have two of them folding at 4.7Ghz and temp never goes up more than 60c. Voltage are about 1.33v, which i think is great.Don't forget to PM, you can easily find it for 299.99$

Comment:
Easily goes to 4.5ghz with only a multiplier change (ASUS P8P67 mb). Megahalem sitting on top with push pull fans. Max's out at 61C on a prime95 load after a couple of hours.

Bought this with a P8P67 Deluxe Asus mobo and G.SKILL F3-12800CL8D-4GBRM Ripjaws RAM.The chip is as advertised and reviewed on numerous forums. It easily overclocked to 4.4 ..103x43 without a single Voltage increase....BUT the temps shot up very quickly under prime 95 and I was forced to shut it down. After removing the cooler and cleaning off the thermal paste...re-applying the paste and reseating the cooler( a very very frustrating job..the idiot who came up with this system should be shot)The BIOS reported higher temp then I was used to seeing under Core2 duo and again Prime 95 brought it up quickly and very very close to cutoff point.So I changed to an aftermarket cooler with a bolt thru system and the temps in idle are 29 and under prime 95 they still shoot up quickly but no where near its 96 celsius cutoff point.

Comment:
like others have said this is one fast intel cpu. provided you have all the necessary components that can supply it the power and stability it needs, you can overclock the heck out of it. great temps under load provided you use a good aftermarket cooler and not the stock cooler. multitasking in windows 7 is simply a pleasure now. can't recommend this enough.

Comment:
So much more price efficient than those 1000 dollar extreme CPUs. Runs very cool as well as long as you get a good aftermarket cooler. Very future proof for any new stuff you'll wanna add.

Comment:
amazing cpu, had this overclocked to 4.8ghz and stable, never reached over 65c during full load with CM v6 muscle cooler.having 4 cores and hyper threading really fulfilled my needs, games never lagged, such as crysis 2 and metro 2033.

Comment:
Bought this with the new asus mobo as a bundle in the march madness sale, this upgrade was phenomenal and I sure as heck am never going back to AMD. The only downside was I had to get liquid cooling for when I crank everything to max, and then livestream it haha its not even a bit hard on the cpu though, just makes it really hot, which is no longer an issue because of the new cooling. I strongly suggest this if you're looking to not have to upgrade your computer for another 5+ years most likely.

I got this CPU on sale for 300$ and I can't start to say how fast it is, I can run everything I want maxed out with it (and a GTX 570)!! I haven't had time to overclock it yet, but i heard they are quite good at it. Very satisfied of my purchase! I would recommend this CPU to anyone who has enough money to buy it!

I have not pushed this chip nearly as far as I am sure it can go, but hitting 4ghz was done with one simple multiplier change at stock voltage. Runs very cool and is extremely quick. This is my first Intel chip with an integrated memory controller. The snappiness brings back memories of my old AMD X2 based system which had this when Intel didn't. The Hyperthreading aspect is also new to me and for an additional performance boost I won't complain.This chip popped right into my Asus P8P67 board, powered up and posted without issue. Very nice speed in everything I do. Paired with 8GB of low latency ram and an SSD drive and you are ready to roll for quite some time. I look forward to pushing this chip a little further in the near future. I am hoping for 4.5-4.6 which I will be quite happy with. Anything else is a bonus. If you want an extremely speedy system without breaking the bank, a P67 based board with this chip is the ONLY recommendation out as of this writing.

Excellent CPU !! Highly recommended! Seem pretty easy to overclock.

Comment:
This next gen Core architecture is fantastic. Should hold me a few years.

Comment:
Great CPU. Matched it up with 16GB of ram and it just eats through everything I throw at it!

Comment:
I have this with my Corsair H70 and my CPU idles around 33-38c... with 50-60c load.What's not to like?

Comment:
Amazing CPU compared with my good old Q6600 this one blows it out of the water in CPU benchmark. Overclock like a beast!! Highly recommended!
