I just wanted to mention that I value any assistance you can provide. I recently upgraded our internet speed to 500mbs both upstream and downstream after having several devices at home—me, my wife, and two children. I didn’t do any prior research; my B550 motherboard supports 2.5G networking, but when testing speeds from the router straight to the PC, I’m seeing around 100mbs down. I’m wondering if investing in a 10 gig network card would make sense so we can better use the full 500mbs connection, or if it would really help overall. Since I’m new to networking, any guidance or advice would be incredibly helpful.

Your board's 2.5gbe NIC handles the connection well. The 100Mbps cap likely stems from a poor cable. I'll test a different cable first. If that works, a gigabit NIC should suffice here.

You don't require a 10 gbps network card. Your card can handle up to 2.5 gbps (2500 mbps), but the router it connects to must also support that speed for communication. If the router only offers 1 gbps, the card will automatically reduce to that rate. Issues may arise from a faulty cable, bent or damaged Ethernet pins, or incorrect drivers. Sometimes software like firewalls or antivirus programs can interfere. To check performance, share a file between your computer and another device—if it transfers faster than 12 MB/s (100 mbps), your card is likely operating at 1 gbps or higher. Visit the manufacturer's site for your motherboard for further guidance.

I hadn’t considered the router side of things, and I’m sure it’s the main reason for the slowdown. Our Belkin router seems to be nearing its 10-year mark, which might mean it’s time for a refresh too.

Highly probable. Older or budget routers often feature just 100Mbit ports, and even if they support gigabit speeds, the processor could struggle with very high-bandwidth applications. A robust router is essential for achieving such performance.

Sadly not so, having 1Gig on the built-in switch does not guarantee the router can move 1Gig of data from WAN to LAN. There's plenty of routers out there that have 1Gig ports and can only handle well under 500Mbit never mind Gigabit. A router needs to have Gigabit ports to push more than 100Mbit, so all having Gigabit ports really means is it probably can do above 100Mbit, not specifically how much. Frustratingly few manufacturers actually tell you what NAT speed (the speed it can move data between WAN and LAN) they are capable of. There's also a difference between routed speed (moving data between public IP address, rarely used for home broadband especially today where IPv4 addresses are in short supply) and NAT speed (converting between a single public IP address and multiple LAN IP addresses).
