broadband speed is impt for all new premium tv's as they are designed to stream and display HD/uhd4k stuff.

if u r quite sure u will be at 8mbps for the next 5 years, save the money, buy the 275x.

or any 1080p tv that u find best value. 4k, hdr models, no need to consider.

but if u think u may get 30, 50mbps soon, then better go for higher grade tv.



the box... if u hv low internet speed, u will also not be able to get good stuff, streamed or downloaded.

so, do not spend too much on the boxe as well.

8mbps will get u some SD, limited HD stuff only.

can't say...

becos it depends on many things.

not just 30 or 100 mbps.

reliable apps like netflix, no problem.

other apps, esp free ones, not so straightforward.

some need special accounts, some need vpn, some very good fro a week then die off, etc..

all these are discussed in androidbox and kodi threads.
