I was reading mixed reviews about the i7 4770k some saying it often overheats and thottles even at stock voltages. I know it is a different platform than z77 with Ivy Bridge. And I use an Ivy bridge at stock and it can get somewhat hot. So if you anyone have the 4770k and had overheating problems let me know. And would you recommend this proccesor over the 3770k or 4820k?
