How does this CORE Duo 2 affect Cryptography and decryption using factorization? Does it cut the time to do a big factorization? Would it render some cryptosystems useless?

I say that Intel needs to find a new archetecture to remove the shared FSB because its the limiting factor now. Having said that, would Clock speed matter in the Dual core market? or now because 2 cores you get faster performance and not need that much clock speed?
