I meant that you have to stress-test the bus connection that you are 
going to use to whatever graphic hardware you
select - you cannot count on embedded hardware being bleeding-edge 
performance, and you are going to play 25 or 30 frames a second over 
that bus -- it is a lot of data, and you have bandwidth (hopefully not a 
problem with pci) and jitter (delay variance) constraints.
