5 out of 5 eggsFor what I do it more than does the trick..

Pros: Great stock clock speed.
Runs quad channel memory.
Bigger L3 Cache than than the LGA 1150 so far.
40 lane PCI express bandwidth.
The biggest plus is it's unlock and has a soldered on die rather than a thermal paste in between the casing and the chip which keeps it cooler so it lasts longer even slightly overclocked.

Cons: 130 watts, but not really a con see other thoughts.
The motherboards tend to be very expensive.
The I7 5820K just came out and is much better at the same price.
2011 socket is kind of dead now, but if I can find a I7 49030k on clearance I'll be ok, because the extreme is an extreme ripoff with the new I7 Es.

Other Thoughts: I had an I7 2600k for almost 3 years and I was getting ready to upgrade, but my CPU blow out before I could slowly save money to get a better system. I had a choice between this CPU and the 4790k, I picked this one because of the soldered on die rather than the thermal paste so I could run this for a while without potential heat issues when overclocking. I already had a quad channel memory kit, so I needed to get a motherboard, a better case, the cpu and a new video card(which I was going to get regardless). I got lucky because I got this cpu through another vendor at a much cheaper price and the motherboard I got a Gigabyte X79-UP4 for $89 as well since the motherboard I got from the other place was an open box at that price and they didn't check for defective pins so they gave me a new one for the same price. If my cpu didn't blow out I would of went with the new I7 5000 series instead, but since I needed something fast since I do a lot of audio/video rendering for the price and what I needed it for I don't regret it. You'd think that 130 watt top out would use a lot of power. Not really. At idle with the motherboard I got it uses a lot less wattage and when I overclocked this thing to 4.3ghz I didn't have to bump up the voltage one bit and with the Corsair H100i system my temperatures idle around 32c and never go above 58c under load.

5 out of 5 eggsFirst Intel I've owned

Pros: I decided it was time to build myself own computer for the first time and my friends were telling me 4770K but I figured I'd try something different and wow....I've only messed with it a little and am overclocked to 4.6 and that's enough for me I love this processor.

Cons: none that I can think of

5 out of 5 eggsBuy it

Pros: Awesome. Have it in my PC and haven't had a single problem, no bottlenecking. My r9 270 can run at 100% usage fine. Performance is close to 4770k however the 4820k is cooler, and has higher clock speed. Great processor.

Cons: Non so far

Other Thoughts: I love it. Haven't had it long, but I love it so far.

5 out of 5 eggsAmazing Upgrade

Pros: Fast, stable, easy to install

Cons: None so far... other than I wish it was free.

Other Thoughts: This upgrade was a long time coming. I've been pushing my system pretty hard since I installed this piece, and I'm not sweating yet.

5 out of 5 eggsPower!!

Pros: - Runs cool despite 130watt TDP
- Powerful (encoded a 320Kbps, 1 GB File Size song in 25 seconds)
- Awesome Overclocking ability

Cons: - None

Other Thoughts: This thing is a beast! I upgraded from a Core i5 2500 and this CPU blew my mind being able to handle anything I threw at it with ease. My example is in a game of Minecraft in an amplified world..... My old Core i5 2500 would get maxed out during normal gameplay and heat up ~65c where under the same conditions this CPU goes, "Haha That tickled" only needing 25% of its total processing power!! Now THAT IS AWESOME!
I can get with a Xigmatec Black Knight CPU Cooler and thermal grease I run temps around 35c idle to 50c max load! Yes 50c max load..... all cores clocked @ 4.1GHz
and oh I normally run this CPU at 4.1GHz BUT IT CAN DO SO MUCH MORE. I hate overclocking but its like a waste of cash not to overclock this beast! I got a stable 4.65GHz before needing to back off.
If you are on the line.... just buy this beast! You will NOT be sad at all!

5 out of 5 eggsExtremely fast

Pros: Unlocked multiplier makes overclocking easier. Extremely fast, even at stock. Runs cool. 22 nm architecture. No heatsink / fan is a plus to me. I never used the stock ones anyway.

Cons: None.

Other Thoughts: Upgraded from an X58/ i7-920 setup to this processor. Paired it with an MSI X79A-GD45 Plus and 16GB of GSkill DDR3 2133 RAM. Boot times are noticeably faster, as are app and game load times. Nothing seems to slow this system down.

Some might say this processor is entry level because if you're on LGA 2011, you might as well get a CPU with six or eight cores. Personally I have no regrets, and I know I can upgrade down the road if I ever need to. This CPU seems to be on par with a 4770K benchmark-wise, which is more than adequate for me at this time.

5 out of 5 eggsi7-4820K

Pros: To be honest I was skeptical about quad core cpus from intel, I didn't see myself buying one since I've been working with AMD most of the time. This fella can chew anything that I trow at it it performs faster than my AMD FX 8350 in any possible way. Runs cool and it uses less power which is awesome, Intel has won me over AMD

Cons: I find no cons so far with this cpu, did not include a cooler no biggie for me I'm liquid cooling it, would be nice if it includes a excelent thermal paste with it but appart from that nothing I can add to

5 out of 5 eggsStep up from the 2600k

Pros: Very happy. Runs even better than my 2600k. Over clocks like mad.

Cons: Did not install its self.

5 out of 5 eggsWorkhorse

Pros: Chews through anything I throw at it with ease. Gaming is the lightest activity this CPU sees from me. Video editing and encoding as well as 3D modeling analysis is where this chip shines. 2011 socket and the X79 chipset is made for being a powerhouse of a workstation. I run CFD and stress/ fatigue analysis simulations with this and it makes my work computer look pathetic.
Overclocking was great as well. I was able to run firestrike at 5GHz with just 1.48 Vcore and never saw more than 70C. This was just stable enough to do the firestrike run and I only overclock while bench testing.

Cons: I haven't found any yet.

Other Thoughts: I use Solidworks for my design use and simulations. If I just wanted a gaming rig I would have gone with something a lot less than this as games are not CPU dependent.
My overclock at 5GHz was just stable enough for me to run Firestrike. My physics score was a 12881 (28% increase) but my overall score was a 7553 (only a 2% increase). I use a MSI X79A-GD-45 Plus MB and a Cooler Master Seidon 240M AIO.

4 out of 5 eggsNot bad

Pros: Easy to instal, stable, ability to overclock

Cons: Benchmarking (Cinebench) shows it is not as fast as other 4 core hyper-threaded CPUs, although that could be something else in my system. Not positive, but most likely the CPU.

Other Thoughts: It works!
