i found core i7-2600k & core i7-2700k with the same price = $300 in www.bestbuy.com
that's the only place available for me to buy
someone advised me to get 2600k because of clock issues in 2700k, i know that 2700k is higher with 100 mhz, so what is the better of them with the same price?
The only difference between the Intel® Core™ i7-2600K and the Intel Core i7-2700K is that the Intel Core i7-2700K runs 100MHz faster. There really is no difference otherwise. If they are the same price without question go with the Intel Core i7-2700K.
