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.

5 out of 5 eggs

Pros: Disgustingly fast. This thing can't be stopped, I throw everything I have at it and it just eats it up. Can get up to 4.7ghz overclocked without touching the voltages, rock stable.

Running in an H440 with the Kraken x61
Idle temps 32~ Celsius
Mild Load 40~ Celsius
Full Load 60~ Celsius

I literally can't think of a con. No real need to overclock because it runs everything I can throw at it at stock speeds.

Cons: None

Other Thoughts: Got this in a deal for 60$ off, totally worth it. Coming from an old core 2 duo this thing is amazing.

5 out of 5 eggsi5 2500k vs i7 4790k

Pros: The reason I changed cpu's is the motherboard.My old chipset z67 was getting old.I run ssd's and need the speed that a z97 can produce.None of this will help me with gaming.I'll still on a rail over what I did,(new mb,video card more ram)but I'm sure it will work out fine.To all that have a z87 MB you will need a bios update before booting this cpu.Good luck to all.I'm sure this upgrade will carry us all to the next upgrade.

Cons: Price as always.I live in The Villages,Florida and I believe I will have the fastest PC in the hood till tomorrow.

Other Thoughts: I won a Intel gaming jersey, yeah! Newegg always rules they sort out any problem you have.3 day delivery.

5 out of 5 eggsWhat can I say?

Pros: It's fast. I wasn't expecting anything less considering the cost. The stock fan cooler is nice and quiet, too, though if you plan on exceeding 4.0GHz please consider getting a larger one to avoid frying the thing.

Cons: I cannot think of anything yet. It has handled my workload like a pro so far.

Other Thoughts: Just be careful with it, man. The pins are very sensitive. Don't man-handle your processor.

5 out of 5 eggs

Pros: Worked great out of the box. Running stock 4.0Ghz. Worked great with my Gigabyte GA-Z97X-UD3H board.

Cons: Runs a little hot at times but that is due to using the stock heatsink that comes with it.

Other Thoughts: Build:
i7 4790k - 4.0Ghz
Gigabyte GA-Z97X-UD3H
Corsair Vengance 16GB RAM

5 out of 5 eggsThumbs Up

Pros: Plugged right into my z97-Pro Asus board and proper timings and runs rock solid. Noticeable increase in speed over my old i7 2600k when performing cpu intensive applications.

Cons: None really. If I had to pick something it would be the sad little cooler it comes with, but that is a given. It would work fine for a regular home computer, but don't expect to use it for much more.

Cons: none at all
