I don't really care about the C2D processor, since most reviews are it is a bland chip without the Santa Rosa chip set. Better, sure enough, but not enough to care about.
Santa Rosa isn't a chipset, it's the name of the platform.
It consists of Merom (eventually Penryn?), Crestline (i965 express chipset) and Kedron (802.11n).
Santa Rosa won't affect performance a great deal.
The faster FSB will make a difference of maybe 3-5%. Maybe a little more in bandwidth-sensitive applications (say, some forms of decompression).
Less than than the difference between Yonah and Merom.
The other big differences are the new graphics core -- which the MBP won't use, the 802.11n - for which the spec hasn't yet been ratified, and is something easily added by changing/adding a wifi card, and the Robson flash caching technology, which is probably the biggest difference.
Note that Crestline is currently specced at consuming ~50% more power than the i945 chipset in Napa. Robson, however, should reduce some of that.
It's quite ironic that after years of Powerbooks getting new G4's with tiny clockspeed boosts, something like Merom is considered "bland"(?)
