5 out of 5 eggsMeets or exceeds expectations

Pros: Top of the line consumer processor when purchased so assumed it would be a performer; and it is. Fairly easily hit 4.7 and runs like a champ; using its integrated graphics for one screen and my 770 for games.

Cons: Price but that is to be expected.

5 out of 5 eggsGreat CPU

Pros: Fast (obviously)

Cons: Stock cooler is bad (of course)

Other Thoughts: I was having voltage issues at first but I'm pretty sure it the issue was on the motherboard. Still was annoying.

5 out of 5 eggsAmazing Performance

Pros: This processor is very fast, runs pretty cool and performs above my expectations. Upgraded from a Core2 Q6600 quad at 2.4ghz overclocked to 3.2ghz build. The difference was astonishing.

My brothers system is a FX8350 with only the turbo boost on and the 4790k smashes right out of the box with no overclock.

Cons: None!

Other Thoughts: Make sure you get a good cooler. The stock cooler can't handle this processor if you stress test your cpu at stock clock speeds.

Cons: none

Other Thoughts: A very good quality product. Wish cpu's would start coming with nicer stock coolers though.

5 out of 5 eggsOnce you go Intel, you never go back.

Pros: This is my first Intel processor ever outside my development machines at work. I am not disappointed.

This processor runs FAST, it runs COOL, and it runs STABLE ENDLESSLY even overclocked and under load.

I would recommend this processor to anyone that is looking to build a performance pc.

Cons: Cons....hmmm.....If you are on a budget, this isn't for you, I guess?

5 out of 5 eggsState of the Art

Pros: So good it doesn't need overclocking.

Cons: Price?

Other Thoughts: @ John G. I wouldn't do that, John. If you ever have to RMA the thing, Intel is probably going to ask you for some of the data/nomenclature on the fan itself. Better keep it in a safe place. Without their mickey-mouse fan in your possession you have no CPU warranty.

5 out of 5 eggsFast and Hot

Pros: Very fast at 4.4GHz

Cons: Take the provided heat sink / fan and toss it in the trash. Processor was running at 90C when stress tested. I installed a Corsair Hydro Series H110 water cooler and now it runs in the low 50's with the fans and pump barely running.
