Don't forget about your network card's bus architecture too. A standard PCI bus (or if you plug a high speed card into a regular PCI bus slot) can not do 1Gbps networking. You'll want at least a 64bit/66MHz bus/slot and ideally PCI-X or high speed PCI Express.

Also, the disks can definitely be a bottleneck for such a network speed. The
links Jaap was referring to don't seem to talk about that.
I would definitely use a separate disk, maybe SCSI 10k RPM. Or a fast SATA.
Have a nice day
