Looks like the E6600 may overclock better then the E6700. Anandtech got 4.0 ghz on air! They also mention that though the X6800 does not oc as well as the E6600 and E6700 that it also allows for a more stable environement for your other components since you don't have to OC the front side buss as much to achieve the oc, if I read this correctly.
