Nightman :
Does anybody know where I can get information about the overclocking performance of the new i5 4690k processor? I'm going to get either it or the 4790k, and I'd like to know if the i7 is worth the extra money. If it does overclock to ~0.5ghz faster, then I'll get the i7, but I don't want to spend an extra $100 for hyperthreading alone. Thanks in advance!
You can try a google search, but these CPUs are brand spanking new. So the only reviews/previews you will see are going to be mostly engineering samples which are not retail chips usually.
I would give it some time for people to play around with the new CPUs before deciding which overclocks better, its not possible to tell currently.
Here is one review of the new i7:
