LOD distance

i'm just interested how far could you generate LODs on mid-low tier PC without lagging?
is it like 2k blocks? 4k blocks? 10k blocks?
let's assume low-mid quality preset

how long would it take to load 10k X 10k blocks of LODs for a mid-tier PC?

what are the maximum distances players managed to load?
are there any screenshots of such distances besides the youtube previews ?
