Fantastic CPU! 7/14/2015 11:13:17 PM

Pros: Rock-solid reliability, and can stand up to extended use.

Cons: None.

Overall Review: I've had this CPU for 4.5 years and it has been in near-constant production use. I turned the machine off a month ago as I noticed that the CPU temperature was around 55C under mild use, blew out the inside of the case with compressed air, blew the dust off of every fan, fin, and surface inside, reassembled the computer, and now the CPU idles around 27-21C, is 38C under moderate load, and sometimes spikes to 65C when running all-out. Solid. Reliable. Dependable. It's been a great purchase.

2 years, no complaints. 6/18/2013 8:52:31 AM

Pros: I've had this CPU for over two years, and it's been great. With HT enabled, I've got a stable OC of 3.8 GHz on a Corsair H80 cooler.

Great for video encoding, 3D rendering, 3D modeling, animation, gaming, and everyday PC use. Basically, it's been an all-around workhorse for all my computer needs.

Cons: None.

Overall Review: Even though it's been long discontinued, it's highly worth considering if you can find one cheap through other outlets.

Nice Product! 12/1/2011 7:39:52 PM

Comments: I have a H70 to cool this monster and it does the job. I'm now building a new set up with a 2600k and still going with water cooling (H100) I hope I will get something close to 4.8 if I am lucky :)
