If you do pure IO workloads, the 4 dual cores are probably going to be as fast
as the 2 quads because of the clock differences.
For CPU bound workloads, the quad cores will beat the duals easily because of
the higher clock speed (and more efficient caching in case of AMD).
The only other things I would worry about is the number of memory slots.
Usually boards that have 4 cpu sockets have a larger number of memory slots
too. So if you need lots of ram, you're better off on that.
