5 out of 5 eggsAwesome i7

Pros: Awesome, it really pushed my 7970. with my Phenom II 1100t I was getting 21,000 on 3dmark06, at the 3.7ghz stock the 4850k jumped it to 27,000. If someone was willing to void their warranty they could probably Over-clock it to 4.7ghz and get around 34,000 marks.

No pins to accidentally bend
No heatsink/fan to throw away or shelf, intel knows you will put an aftermarket one on.

It's a very stable screamer, and has reputedly high overclocking capabilities.

Cons: It doesn't make coffee and it doesn't rub my tummy.

Other Thoughts: It was ordered for a rebuild in tandem with:
ASRock x79 Extreme4 LGA 2011 Motherboard
Cooler Master Seidon 120XL

All components mated flawlessly.
Make sure your cooler is rated for the 2011 socket as it requires brackets with a different hole pattern than previous sockets.

5 out of 5 eggsAmazing CPU

Pros: This chip is amazing in every aspect of the word. The OC this thing is capable of is second to none. It was a toss up between this and the 4770k and I am glad I went with this.

Cons: 2011 Socket is a little more expensive for a build but worth every penny if you are going to use it.

5 out of 5 eggsPowerhouse!

Pros: This processor is incredibly powerful. I was in between a 4770k and this when i was researching. I am sold on the 2011 socket. Overclocking has been a dream with this cpu. 4.4ghz on air cooling with a max. temp of 52c. This processor downclocks when not using full power effectively saving on electricity. This cpu will cost you more in the long run with its higher tdp but opens me up to a hexacore upgrade without switching mobos. I have had no issue playing games at max settings with programs running in the background. A true multitasker.

Cons: Plain and simply the power draw. If you plan on basing a rig around this cpu then you need to invest in a high quality power supply and aftermarket cooler.

5 out of 5 eggsExcellent CPU!

Pros: * Quad Core with Hyper-threading, @3.7GHz (3.9 turbo)
* Runs Cool if you have a decent Cooler, doesn't come with one.
* Extremely fast for the price, lots of nice features on this chip.
* 10MB L3 Cache, doesn't get much better than that.
* Unlocked, overclockable to whatever your cooler can handle.
* Supports my 2133MHz Ram, in quad channel mode.
* Hey, it's Intel.... BUY IT. Don't be cheap and go AMD thinking you're getting more bang for your buck, its like buying a Ford when you could pay a little extra for a Ferrari.

Cons: None as of Yet.

Other Thoughts: This thing is amazing. I built my new gaming PC this month which included this CPU (obviously) and let me tell you... it was worth it. I upgraded from an AMD Phenom X4 9750 @ 2.77GHz overclocked. This thing BLOWS away that old AMD, and even new AMD chips. You want your money's worth, you buy Intel. AMD is something you buy when you don't want to play recent games, and you certainly don't buy AMD for future strength. I would like to warn the people out there that don't read anything about the parts they're buying.... this CPU does NOT come with a cooler. This is for a reason. Intel doesn't MAKE a cooler big enough for this chip, it needs a high performance cooler to run correctly, you put something small on there and it will burn up. Liquid Cooling is the best choice for you if you're gonna overclock this, but you can just buy a large air cooling setup as well. This cpu is very worth the price, put it with a good motherboard, GPU, Ram, and PSU and you'll be set! Thanks Newegg and Intel!!!

5 out of 5 eggsVery Quick!

Pros: Very cool running with balanced loads. I was able to safely run this at 4.9GHz (4.9, 4.8, 4.7, 4.7, in order of their respective cores) and at maximum load, I don't break 49°C. At normal loads, it cuts power and runs at 2GHz at 30°C.

Cons: Zip

Other Thoughts: Test Software Provided By ASUS ROG.

5 out of 5 eggsPOWERFUL!

Pros: Consistently benchmark'd in top 0%! Even when not overclocked, when testing I received several notices from sites like PCPitStop that it was the fastest CPU tested at the time, some of my tests being the fastest results PERIOD. Also, top scores on futuremark benchmarks with only the extreme versions beating it in comparison.

Completely floors anything remotely close in price. Which is good!

During general use i rarely see more than 3% of cpu resources used. Even when fully utilizing the processor I see little lag during general use of the computer, it just handles it!

The 4 channel DDR3 integrated makes an immediate difference! That's one direct memory access channel per processor core, so when paired with 8 sticks of memory you have 1 stick per processor thread! To say the least, it can handle data fast, and lots of it!

Cons: Motherboards can be more expensive on initial investment. But new technology always is, and the prices are coming down.

Doesn't have integrated video support, but that's a non issue for anybody that uses a real video card.

Other Thoughts: Besides dropping a grand on a processor there's just no beating it!

5 out of 5 eggsbest cpu for its value

Pros: -It works very well never had the compter bug or anything
-cheap for its value i was gonna go and get the 4930k but almost twice the price so i took this one and even there it can do anything no problem

Cons: -compared to a LGA1155 chip this one uses quite a bit more power.

- It gives out quite a bit of heat so get a good water cooler OR a good air cooler

Other Thoughts: very satisfied with my purchase i plan on keeping it for 3-5 years

5 out of 5 eggsGood chip

Pros: Decided to take the LGA2011 jump with this most recent build, I'm pretty satisfied with the speeds. However, I keep thinking I should have saved the cash and gone with an LGA1155 and an i5 chip. You lose out on a few pretty major features, but it's not really that huge of a loss.

Cons: None as of this time.

5 out of 5 eggsEasy to overclock

Pros: Easy to overclock up to 5.0 GHz with water cooling of course. Purchased it togheter for a new gaming rig with a Gigabyte X79-UP4 mobo. And 64 GB of RAM.

Cons: Not very stable. It has its days

5 out of 5 eggsGett this CPU!

Pros: I waas able to OC this thing to 4.4GHz without even trying! Runs stable and fast! I have this in my most recent gaming build and went with a LGA2011 socket over a LGA1155 just to get this processor. I am using Liquid Cooling and have yet to see the temp on this thing go over 55*C while benchmarking. Paired with Quadruple channel memory, this thing is blazing fast!!

Cons: None at all!

Other Thoughts: I would definitely recommend going with the LGA2011 socket for a gaming build. I did a ton of research before buying and a lot of people suggested the LGA1155 socket due to pricing concerns...but this set-up is AMAZING!
