How about using a Core 2 Duo Windows 10PC with 3GB RAM as your web browsing machine?

I still keep mine around, partly for that reason.

(I also wish the developers used underpowered hardware for their work. Then, for once, "if it runs fine on my hardware, it'll probably run fine on yours" mantra would be true — and latency would far less likely to be as atrocious as it is)
