I don't think I have seen 10G ethernet network card in consumer grade hardware even recently. 10G is there in core infrastructure for a long time. But only until recently you see 2.5Gbps in endpoint devices. (Probably 2.5 makes more sense to a RJ45 head cable)

And also I don't think 10G routers/switchs ever use pure software based solution to handle the traffics. They are all hardware based or mixed solutions.

It's amazing that memory bandwidth / cpu speed / core counts grows so much that makes this even possible. But it still isn't a good idea.
