No - the current PCI bus is 32 bit as well.  The bus from the CPU to
memory is 64 bit on a Pentium.

None of this is really relevant at all.  The bus size makes no real
difference.  In fact, the bus between the computers is typically
Ethernet, which is exactly ONE bit wide.  The simple fact is, you pick a
block of data and send it out over the Ethernet card.  On the other end,
it comes into memory.  There's no question that at a hardware level,
communication is possible without getting data duplicated and such.  If
the duplication is taking place, it's purely a software problem,
unrelated to bus sizes and such.
    Later,
    Jerry.
