Trying to capture 8 full resolution streams on one PCI bus is probably
impossible, but with a NIC or HD controller on the same bus, forget it.

You'd need to get a chipset with multiple busses and put the capture card
on its own bus.

Or get something like viewcast's multi-bttv cards that use a PCI to PCI-E
bridge.
