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).

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 :)
