In order to go from 360p video 15 years ago to 4K HDR today, I have upgraded from a 2mbps 802.11g WiFi on a 1366x768 display to a 200mbps connection on 802.11ax and a 55 inch 4k television.
The experience is quite immersive and well worth the upgrade that happened very progressively (WiFi 5 1080p then WiFi 6/7 4K).
At the same time, we had cheap consumer gigabit ethernet, and still have cheap consumer gigabit ethernet. 2.5 is getting there price-wise, but switches are still somewhat rare/expensive.
Emphasis on "somewhat" - I was able to build a 10GB backbone for my NAS and such for less than $200 or so with a CRS305 and some direct connect cables; looks like the CRS304 would have made this even easier ...
To be fair, I only started this because the dock I got had 10G - https://www.owc.com/solutions/thunderbolt-pro-dock and I saw some 10G cards on eBay cheap and my old Nortel switch had a 10G uplink and ... well, you know how it goes!
