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.

5 out of 5 eggsIntel Core i7 Haswell Quad-Core 4.0GHz LGA 1150

Pros: The best processor I have ever owned
4.00 GHz
8 threads

Cons: I always see postings for AMD processors that have more cores, yet the prices are cheaper. So basically the only con I have is the price. In most cases, you get what you pay for. (It is worth the price... for now)

Other Thoughts: I believe this is one of the best, if not the best proc you can get for a LGA 1150 socket mobo

5 out of 5 eggsAmazing

Pros: I changed my build from a FX 8350 water cooled to this. I'm running it air cooled and it still gives me lower temperatures, not that I didn't know that would happen but just stating it.
Great overall product, VERY fast, reliable, low power consumption.

Cons: Nothing really. Well.. price could be better.

4 out of 5 eggsNice CPU despite Intel's deception

Pros: Very fast, stock 4ghz is very nice.

Cons: Very, very hot even at stock.

MOST will find it very difficult to get this to 5ghz, especially on air, despite the totally bogus claims by Intel.

If you're buying this for its fictional overclocking capabilities, look elsewhere.

It's a cash grab, nothing more.

Other Thoughts: Had to delid just to get decent temps, even at stock.

Intel's new "Next-Gen TIM" is garbage and poorly applied. A large air bubble was partially responsible for my high temps.

2 out of 5 eggsold Ivy bridge did better

Pros: None

Cons: Over clocked on my new ASUS MAXIMUS VII HERO
Corsair H 100i
the best is 4.4 my old 3570K would go to 4.6
This must be just a low end chip

Other Thoughts: Should have gone with 4770K instead

5 out of 5 eggsBeast of a CPU

Pros: Upgraded from a 3.4 ghz to a 4.0 ghz with my new comp, and believe me it makes a night/day difference. Very fast and very efficient.

Cons: Price is not worth the upgrade, you are better off overclocking a lower end CPU.

5 out of 5 eggsBest Mainstream

Pros: Recognized with correct voltage on an MSI Z97 Gaming 5 Mobo. Very fast. Stabilized my FPS in all games substantially, (higher FPS lows). Upped my FPS in all games, most notable is WoW by 30 frames.

Multitasking no longer slows down my PC, stays snappy at all times running games, web, music, file backups, downloads, installs, all at the same time.

Cons: None.

Other Thoughts: I went ahead and pulled the trigger because I didn't have the patience to wait for Broadwell, and the old Phenom was too noticeably aged to keep gimping it.

Blows my old AMD Phenom II X4 965 out of the water.

It's overkill for what I do (gaming/gen use), but it's nice to know I can do a lot more if I wanted to.

HD 7850 OC'd bottlenecks this thing pretty bad, but an upgrade is slated for AMD 300 series. Even with the bottleneck, I stay above 60 FPS on most games.
