3 out of 5 eggsRMAed

Pros: Good from use i got, spent 3 weeks determining it was the issue. To intel's credit their call centre rep was superb, babied me through trouble shooting and helped me confirm processor was issue. New Egg call centre was also superb if you are ordering more then 5 times a year would recommend

Cons: Cooling unit with it does not work don't even try, buy good paste and better cooling unit with build, even games like FTL will send CPU too 55-65

5 out of 5 eggsBeast Mode Activated

Pros: Amazing processor. Glad I did the switch from AMD, I even got better performance out of my GPU!
Overclocked it to 5.0 with a H105i.
Has not given me any issues so far!
Definitely worth it if you only plan on using 1 GPU x16.

Cons: Can't run SLI/Crossfire at x16/x16.
Stock Fan is not that bad but definitely not worth it if you are OCing.

Other Thoughts: I went from a Full AMD Build that was pretty beast using a 7970 with 16gb of RAM running at 1600 and an SSD. I would cap out in WoW at around 45FPS in Cities and 60FPS in world. In DayZ SA, I would never see above 30FPS, MAYBE 45FPS in the open.

After switching to this CPU and changing the motherboard, I was hitting 60FPS across the board in both games no matter where I was. Keep in mind....I Only Changed The CPU and Motherboard. The GPU, RAM, and everything else remained the same.

This CPU is beast. It already hits 4.4 so you really don't have to OC it for anything unless you are planning on rendering like 4K Movies or something. And if you ARE planning on doing that....spend the extra money and get the new 8 Core / 16 Thread i7.

5 out of 5 eggsTop of the line, without a doubt.

Pros: Thoroughly capable of doing much more than the usage I put through it (gaming, game recording, streaming, and mild video editing). Underclocked this guy down to 3.5Ghz /w 4GHz boost. Lowers temps at idle & load substantially, thus extending it's longevity without any dire loss of performance whatsoever. Happy customer :)

Cons: Despite the underclocking I did, the premium we pay for it should include a higher quality air-cooler to keep the temps down that come out of this computing monster.

5 out of 5 eggsIntel i7 4.0 GHZ

Pros: Great CPU. Fast, powerful and runs everything with no issue. Using stock cooler and temps stay low. Worth every dime I paid.

Cons: No cons.

5 out of 5 eggsGood CPU--can't overclock with stock fan

Pros: Fast
On-board video works fine

Cons: The stock fan is good enough, but if you're going to overclock even slightly, you need a better fan.

Other Thoughts: With the stock fan and not overclocking, the CPU temperature hovers around 60 °C playing Skyrim. To see what would happen, I overclocked to 4.6 GHz with the stock fan, and the CPU ran fine at light load but overheated in a hurry with a heavy load.

5 out of 5 eggsHappy

Pros: I'll make this as basic as I can.
It delivers what it says and like the title says Im happy with that.

Cons: As of this date, none so far.
If that ever changes I will update but dont expect I will have to.

2 out of 5 eggsDisappointed

Pros: It works. All comparisons below are standard installs - NO overclocking.

Cons: I can't begin to tell you how disappointed I am in this chip. Two years ago, I got a 13% improvement in the 3770K over my previous 2700K - both 3.5GHz. When I moved "up" to the 4790K (4.0 GHz), I was fully expecting another 13% bump. Instead I got a 3% bump and some math functions (Eratosthenes sieve) are actually 12% slower!!

Other Thoughts: So I suspect Intel mislabeled the chip and/or they are trying to mislead us as to its actual speed. I also have access to a 4771 - which is about 1 - 2% slower than the 3770K.
