There isn't an "internet" card. They all function similarly, providing a link to the LAN that eventually connects through a router, modem, etc., to the internet. It will certainly assist you, as even a device limited to 100Mbps can achieve 1Gbps and beyond up to 10Gbps (though higher speeds require more advanced hardware which is costly)
With a 200Mbps connection, a 10Gbps NIC won’t boost your speeds beyond what a 1Gbps card provides. To use the 10Gbps NIC, you’d need compatible devices on your local network and infrastructure. Most consumer networking gear is currently 1Gbps or older. Unless you intend to set up a home server with a 10Gbps NIC and related setup, opting for a 1Gbps NIC is more cost-effective.
Essentially all NICs function as internet-enabled devices. They serve as a gateway to connect to a network and ultimately reach the internet, provided the network itself supports internet access.
Which board are you using? If it's only 10/100, you likely need a fresh system, not just a new network card. Gigabit was the norm ten years back.
Another consideration is the tools in use, like the router and switches, as these might also affect performance.
