We have a 5gbps pipe; routinely download games from Steam at >3gbps; when I had to reinitialize my cloud backup it was >4gbps. All of this without impacting anyone else on the pipe.
Yah, our P95 bandwidth is just a few megabits per second. But it's not that expensive and routinely saves me a few minutes here and there.
10gbps on the LAN is more broadly useful. Pegging it for a file share is a daily occurrence.
Also storage has gotten super expensive lately, and rather than upgrading my machines/consoles I've been offloading games and downloading them as needed and now am routinely downloading dozens of GB just to play a game.
My gaming time is limited so the faster the better.
