long time user 4/29/2015 10:43:17 AM

Pros: I have ran this cpu since 2012 with zero problems... I have had it over clocked at 4.75 and ran it at 4.5 on air cooling for well over a year with great temps .. and again zero problems. oh i bought this cpu for $300 dollars and the price now at same store is $430 dollars so it went up in value. at the time was amazing value.

Cons: not much for cons ...3yrs later and i still am not looking to upgrade, i think they should of kept this at 300 dollar value and not be gready .

Pros: Will run whatever you want without breaking a sweat. By far the fastest CPU I've ever had the pleasure of using and definitely my go-to for future builds. Whether it's gaming, video rendering, or just a showpiece this is the CPU for the job.

Cons: I no longer need to turn the heat in my house. Oh and it's a bit expensive, but hey you deserve it. Treat yourself.

Overall Review: It says Quad-Core but the one I received is an 8-Core. Fine by me.

Great 11/29/2014 7:36:30 AM

Pros: This processor has been the centerpiece of my home server for two years. Underutilized for what it is asked to do, which is stream media and backup home computers. Supermicro x9sra server board has been right there with it. Couldn't be more pleased.

Cons: Expensive at the time

Overall Review: This chip is not a traditional chip and requires a specific type of heat sink. Research that before you buy and save yourself a return.

Works great in my server. 7/4/2014 9:26:30 AM

Pros: I added this to a custom server I built, Fast and reliable. The only thing I plan on upgrading on this server any time soon it replacing SATA with SSDs so this processor will be used for another couple years. Intel Rocks.

Cons: None
