<< in regards to the clip on this heat sink, i don't think it's really an especially bad point, as it's the same as almost any heat sink out there right now. while a better clip would basically make no negatives points for the gc68, as long as you're careful and make sure the screwdriver doesn't slip while ur installing the clip, it shouldn't be a problem at all IMHO. >>
Lordbob99 hit it on the head, the GC-68 is awesome except for the clip. Just get a small screwdriver, and put duct tape around the edges of it to protect if it slips by mistake. It's really not that hard to install once you get used to it.
