Why do you need to have low bitrate?
There are lots of techniques to hide latency.
I don't get the thing about the GPU: even rich people don't necessarily want to bother with owning a GPU thing. And whether fast internet is expensive depends on where you live. Here in Singapore 10 Gbps fibre to the home starts at around 20 USD per month; and we are in a really high cost of living country (we usually topped charts of 'most expensive city to live in').
