The only advantage of separate systems would be the increased CPU and bandwidth available. As long as you are using a fast enough processor and memory, you should be fine. A normal 32 bit/33 Mhz PCI bus peaks at about 600 Mbits/sec. Double that for 64 bit and double again for 66 Mhz (PCI-X). PCI-express, not sure yet.
