Not seen anyone OC the 860, I assume it's going to go the same way as the i7-940.

The Speed stepping in the i7 860 is superior to the LGA1366 i7, as well as the i5. This is the feature that automatically overclocks individual cores on the fly as needed, when not under full cpu load. It is FAR more aggressive than the i5 speed stepping, so that may be a consideration in your decision.
If you don't plan to OC, then the 860 will perform a LOT faster in general use than the 133mhz indicates.
I got the impression OP would be OCing in which case turbo would be enabled. Would normally agree with you though.
