Until you have fast fibre and realise right now that even 500 is a complete waste of time...80 000...well you get the drift.
The wifi tech (!!!) isn't fast enough to keep up with a 500mbps line so you've got a bottle neck in your house (or you need to throw ethernet cables everywhere). And even if wifi could keep up very few servers can sustain that kind of throughput anyway. Even stuff like news downloads tops out below 100...
Only reason I'm on 100 instead of 50 is that the packages are linked to daytime data cap & its cheaper to get 100 than buy more daytime data separately.
