Use the onboard controllers, on most boxes those are a seperate bus to the PCI bus. > limiting factor. CPU isn't the problem. I think my bus is running at > 66mzh. Probably anything you can buy now will make a difference Its normally PCI bus bandwidth (and fairness) as well as meory bandwidth on low end boxes. Obviously it depends what you are doing. Another trick is to drop the drives to UDMA0 (either by using a 40pin cable or in software with hdparm) as that tends to even out the bus usage and leave gaps for the mpeg engine.
