From the info that I have, there will only be a 3110 and a 3120 in the 45nm parts.
There are 2.33 and 2.66 GHz single socket Xeons that have 1333MHz FSB but they are on 65nm and only 4MB cache (3065 and 3075)
HTH :)
XBit have some comparisons on Dual cores (only at stock though). Here - http://www.xbitlabs.com/articles/cpu/display/dualcore-shootout_4.html#sect0
