I would defiantly stick with PCIe for 5 NICs. Additionally Realtek
NICs don't offer the best performance and their drivers are hit or
miss. The Supermicro board has Intel PCIe NICs onboard and a PCIe
expansion slot. This should give you full performance depending on the
Atom processor. It really comes down to if you are just moving packets
or needing to do packet inspection.
