The 3B+ has gigabit ethernet, but it's still on a USB 2 bus, so you're going max out at ~200Mbps instead of anything close to 1000Mbps. That's still enough for maybe 10 simultaneous 4k streams, so you should be fine.
Reading and writing to an SD card becomes a bottleneck at that point anyway, so true gigabit ethernet probably wouldn't be that noticeable.
Cheers, I'd assumed that they'd upgraded the bus along with the ethernet.
The bigger issue than streaming will be whether it will prove a bottleneck for simultaneously downloading (at 200Mbps I think) and writing to a network drive (and whether that is really important to me).
Yeah, good point about the rest of the hardware components, and the streaming rate. I recall that Netflix "Ultra HD" is around 25Mbps, so there's plenty of headroom.
