I bought the MSI X570 MEG ACE and noticed quite a few motherboards have two LAN ports. One is labelled 2.5G and the other is Intel gigabit ethernet (at least on my board) and I couldn't quite figure out why it has two, and which one I should choose given I only have gigabit ethernet anyway (i.e. it's not the newer one). Any thoughts/advice? I have my network switch near my PC with a few empty slots so I could plug both cables in, but I fail to see how that would achieve anything.
