4 GiB should work without causing major issues, but it unlikely
provides any headroom and most likely already will be a serious
bottleneck. 8 GiB not necessarily does provide headroom, but could
already provide some headroom. Depending on what you want to do, even
less than 4 GiB still could work, but it likely will be a critical
bottleneck.

As already pointed out, I don't need more than 8 GiB, but for a new
machine I would chose more than 8 GiB. How much more would depend on my
financial condition, when I build the new machine. It would probably be
way more than 8 GiB, since other than overdone CPU headroom, which
likely could have side effects, such as unreasonable high electricity
consumption, probably even when being more or less idle, overdone RAM
headroom probably doesn't harm much, if at all. It's a little bit
guessing based on experiences I made in the past, it might not
necessarily apply to modern machines.
