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]
