gaming is more towards latency la. Cos need exchange data in real time

Streaming/browsing is the connection speed, 300mbps is more than enough to view 4k video.

Anything above 300 is for NAS, at that point upload speed more important than download.

If u want smooth gaming better to invest some $$ for vpn. exitlag works really great the last time i used. support most online games. Easy to use and not expensive. cheapest is to create new account and then sapu the annual package during black friday. Those black friday deals only work on new account, so need register every year.

That's my 2sen la as plebian.
