So it sounds like TB3 + USB4 would be a good docking station, and TB4 just makes it a bit better. So I shouldn't be too worried if I upgrade my laptop and it only has TB3.
Finding it hard to keep up with tech lately :D

Right now I use a machine with USB-C for video out at 1080p one monitor. But I don't use an eGPU with that, and its officially an Android device.
I got 2x 1440p monitor and won't upgrade either any time soon. So I suppose if I were to use both of these, I'd be fine with TB3 and eGPU?
The short answer for Thunderbolt 4 over Thunderbolt 3 is "a second 4K display" thanks to double the PCIe bandwidth, 16Gbps vs 32Gbps. (The main data channel is 40Gbps in both.)
USB 4 is actually a bit more constrained than Thunderbolt 3, at 20Gbps data channel, and no guarantee of PCIe bandwidth.
> Thunderbolt 4 guarantees support for one 8K display or two 4K displays. A USB4 port can only support one display with no mention of resolution minimums. And even that isn't required as some USB4 ports will not support video at all.
