That's one use, yes. They can also be "teamed" which increases throughput. Multiple NICs (network interface controllers aka Ethernet cards or ports) can also be used for specific purposes that are beyond what you're wanting to do.
For basic internet browsing, HTPC use, and file sharing between PCs, dual NICs aren't needed. This would add multiple layers of complexity and really takes networking to another level.
