If you should use them in a PCI slot yes, not if you use them in a PCI-X or PCI-e slot (although you could saturate a PCI-e x1 with 4 gbit ports I think). >> >> > > Depends mostly on if you are using PCI/PCI-X vs PCI-express.

The Intel Quad cards don't fit (and don't then) in a single PCI slot. The Intel Dual Gbit cards do and you can saturate a PCI slot with it quite easy :) Regards, Michel
