Considering that this CPU is currently costing around 80 usd on aliexpress & ebay, outperforms an 3970x intel i7 and officially supports 4 channel DDR3 RAM at up to 1866mhz, it's really hard to beat the value of this chip. Possibly the best price to performance of any used CPU in the market today, in 2020. [Mar '20 jetjix]

MORE DETAILS

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
