If it reduces the parts count by one package, let the CPU do the
graphics. If the memory bandwidth is going to be saturated anyway,
the memory cycles spent setting up and communicating with the
graphics coprocessor will probably swamp out the benefit of having
it. The hardware design and the software design will be simpler
(read, "more likely to work in your lifetime") without it.
