I thought we were talking about building a router? The lack of PCIe cards is a good reason to consider a PCIX machine. On the systems that we have, the 1x PCIe ports are a lot slower than a PCI-X card in the slot. You need 4Gb/s of throughput to handle a gigablt router. (1 GB/s full duplex times 2). 1x is 4Gb/s maximum. In my view, you always need twice the bandwidth on the bus to avoid contention issues.
