When will SSD speed start making a difference in gaming?

When pcie gen 4 SSDs came out, people said it won't matter for gaming compared gen 3 SSDs or SATA.

Now that gen 5 SSDs are here people say it won't matter in gaming compared to gen 4.

So my question is, are those people actually right? And if so, when will SSD speed actually start to matter?
