On the surface, it appears that the only difference between this and i7 2600K is the 100 Mhz -- which is almost negligible. But its not, explanation below.
Before reading further, if overclocking is not a must for you, buy the i7 2600 (without the K) - there is absolutely no difference for you.
But, if you are overclocking -- this is what you want to get.
Why? Because this chip is made from a very high grade of silicon - which makes it a superb overclocker.
If you get a 2600K, there is a cha...

I Am Using This Processor Since It Available On Flipkart.

I've been using this for the last 2.5 years now.
The problem with this is that the stock fan is useless. The temperature hovers at 80C when using at the 3.9Ghz, it gets above 75C at the 3.5Ghz stock speed which is a big problem. I'm forced to run it at 3Ghz or below to keep it stable below 70C.
This was a disappointing buy for me.

please reveal this motherboard for us > " Core i7 3770K ", this motherboard has same as above, but its 3rd gen motherboard, and its need low W to run. and it's memory supports up to DDR3-1600 but above processor supports upto DDR3-1333.
