Right, but who has the resources to rent compute with multiple GPUs, this is a gaming setup, not office work, and the op was talking about racking it.
All of those services offer an inferior experience to being at the hardware, it's just not the same experience. Seriously, try it with multiple 1440p 144hz displays, it just doesn't happen work out well, you are getting a compromised product for a higher cost. You need a good GPU (or at least a way to decode multiple hvec streams) in in the client, and so, you can run a standard thin client.
'low latency' is a near native experience, I'm talking, you sit down at your desk and it feels like you are at your computer(as to say, multiple monitors, hdr, USB swapping, Bluetooth, audio, etc, all working seamlessly without noticeably diminished quality), anything less isn't worth it, since you can just, use your computer like normal.
