your best bet is to upgrade.
so no the newer chips wont fit because you have a different socket.
Socket 478 also has those specs though... the only place I think he'd find one is on eBay, there ARE 2.6 400MHz FSB chips though, I've seen them... Get a Pentium 4 2.4"A" if you can, they're really good overclockers.
