Q9450,s who knows what they will do, the x8 multi means you'll need a 500 fsb to reach 4 GHz, is it worth it? haven't even seen an engineering sample, so can't say.
If I were a Q6600 owner (I'm not) I wouldn't be rushing out to upgrade to the Q9450 there are too few apps available that will push a Q6600 at the moment so why bother.
If your talking about the Wolfdales, the E8400 & E8500 is what I would be looking at.
