Intel I7 2600K or 2700K Sandy Bridge CPU's were and are the best chips (mainstream) that were ever marketed to the public...! The IHS were soldered and better TIM used than the next gen Ivy Bridge 3770K which had to be delidded and better TIM used to approach the Sandy Bridge...
Also, they ran hotter due to Intel cheaping out on building IB. Furthermore, almost all the architecture went mainly into the graphics..., If you paid 350.00 - 375.00 for a CPU for Gaming and Media you were certain to invest in a GPU and not use the on board graphics... Anyway I have OC'd them to over 5MHz on air stable however, not wanting to ruin the longevity of the chip I could always get a solid OC of about 4.5 - 4.8MHz on the chips, still running 4 of them on 4 of my personal PC's and they are like the day I first built the PC...
In my opinion Intel's Sandy bridge CPU's were the BEST chip ever offered for the money, the list of why this SB architecture is - was the best CPU one could write a book on it! Moreover, as mentioned above the 2500K SB even though an i5 still ROCKED and was just as good at gaming as the 2600K & 2700K's however, I always spent the extra and went with the i7's for the best all around (media) being a biggie with me.
