This will give you 5 Gigabit Ethernet ports (2 on PCIe and 3 on PCI) and a free PCI slot on which you can put up to 4 more. Of course it all depends on the needed concurrent traffic.
pci is a shared bus with a max of 2 gigabits. you'll see a gigabit but never see two or more.
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.
