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]

The Intel Core i7-3770 is an Ivy Bridge processor. With four cores and eight threads the 3770 has excellent single , dual and multi-core performance. Comparing the 3770 to the 4770K shows that the 4770K leads by 11% at stock speeds and, thanks to an unlocked multiplier on the 4770K, by 15% at overclocked frequencies. The i7-3770 has a very strong performance profile which includes multi-core capabilities that are likely to be overkill for the majority of desktop users. Comparing the 3770 to the 3770K shows that the unlocked 3770K allows for, on average, an additional 8% increase in performance. [Mar '14 CPUPro]
