I get like 20mbps down and it's fine. Netflix only recommends 15 Mbps for 4k streaming. Lol, looking at websites and stuff is certainly not a problem. About the only time speed has ever been an issue is if I need to download a large game on steam. But I attribute that more to developers just being too lazy to actually optimize their games. I shouldn't need to download 50 gigabytes to play some game when I'm just running at medium settings.
