    It is SMP, definitely.  If one were to ask the question... how many
    cpu's is enough?  The answer is probably around four for any general 
    purpose computer.

    The biggest advantage a GPU has is its ability to process work in 
    parallel, either with parallel processing elements or with pipelined
    elements.  Because of this a GPU can do far more work then a CPU
    within the bounds of its capabilities.

    GPU makers have recently started trying to incorporate general purpose
    computing elements into GPUs, but I think this effort is going to be
    fairly short lived as consumer computers start to get more cores.  My
    guess is that GPUs will evolve better GPU<->CPU ABIs instead and most
    of the supervisory workload will shift back to the CPUs.  Pretty soon
    game makers will be able to *rely* on consumer machines having 2 or more
    cores in them.  There won't be any more single-core consumer machines
    two years from now.
