You are confusing older cpu models with newer cpu models;
There is no such thing as a C2D 2.2GHz since the T7500 (Merom 65nm), and the previous generation Penryn 2.6GHz T9500 has a 800FSB. Both are still more expensive ($241/$530) than the newer 1066FSB penryns (for the montevina platform).
P7350 2.00GHz 3MB cache 25W 1066FSB 45nm $1XX
P8400 2.26GHz 3MB cache 25W 1066FSB 45nm $209
P8600 2.40GHz 3MB cache 25W 1066FSB 45nm $241
T9400 2.53GHz 6MB cache 35W 1066FSB 45nm $316
P9500 2.53GHz 6MB cache 25W 1066FSB 45nm $348
T9600 2.80GHz 6MB cache 35W 1066FSB 45nm $530
