D0 is supposed to bring a few things to the table:

1) More consistent overclocks (no large variations in overclocking ability like with C0 chips where some can do only 3.8GHz and others can do 4.6GHz).
2) Slightly lower voltages for same clocks.
3) More balanced temperatures (related to voltages above).

Generally, D0 will not do much for improving the overclocking ability unless D0 was based on the best of the best of C0 in which case most D0 will clock better than an average C0.
i think the Intel is working for improving the overclocking ability , things have changed since AMD reached more than 6Ghz with their cheap quad
