is it worth the risk to delid ? No , and very risky.Gains most of the time are minimal.
While I agree its very risky, I've seen gains as much as 40 degrees on each core on an i7 3770k after delidding. It really depends on your luck. The guy I saw was getting 90 degrees at stock clocks undervolted.. but still. The gains are there to be had. Be aware you are throwing your warranty out the door and any resell value is mostly gone. Of course if you successfully delid your i7 3770k and don't want it after 4 months I'll happilly buy it off you
