I would like to purchase the SB i7-2700k over the IB i7-3770k because I heard the temperatures for the 3770k is all over the place. I would like to overclock but not spend to much on cooling. So what motherboard would you recommend me to get? Or should I just get a z68 3rd Gen. What downfalls would i have running a Sandy Bridge CPU on a Z77 motherboard meant for Ivy Bridge?
