tl;dw - I can get five 1 Gbps network interfaces using an Intel I340-T4 PCIe NIC, but I can only get a maximum of 3.06 Gbps throughput using all five interfaces at the same time.

You could use this setup to build a custom router or switch using OpenWRT or pfSense, or to run other specialized network setups for multiple-interface webservers, bandwidth metering, network bonding, or more!
