There really isn't an answer for your question. The load implied by
being a DC depends on the number of clients and how heavily they are
used. If you have only a hundred or so clients, in my experience, the
load is pretty mild [for modern hardware/networks].
With Samba3 domain control there isn't really a BDC/PDC distinction.
Every box is a PDC that operates in parallel with the other DCs. That
is a bit different than a true NT4 domain.
