If you just want to use it with National Instruments' LabView, ISA bus
is enough. But for RTL, PCI bus is better. So buying PCI you can think
you buy a more-compatible-card, that is, you can use it on other
computer platform. And PCI is quite faster.
But really I don't understand why John emphasizes the use of AGP. The
difference from PCI is not really big enough, I think - including the
publicity campaign made from intel, of course.
