TP-Link TX201 (2.5GbE PCIe NIC)
A beginner-tier 2.5GbE PCIe NIC built on the Realtek RTL8125, a low-cost way to put an older motherboard on 2.5GbE. It's a sensible upgrade for boards still stuck at gigabit. There's no reason to buy it if your board already has 2.5GbE onboard, and it won't help a 10GbE backbone.
