I'll second this. Getting an SSD was the last big "oh shit" upgrade. Now the only things I recognize myself waiting for are really heavyweight programs, like yes, gaming.

While there is often a perceptible difference between a SATA SSD and an NVMe, it's nothing compared to the gap between a spinning disk and any reasonable SSD.

If you're doing anything on the web, a good adblocker makes a big difference.

If you have 'enough' RAM, more doesn't help.

For most tasks, CPUs are wasted most of the time. 2 3Ghz x86-64 cores are good enough not to be noticed on a general desktop.

Latency remains more noticeable than bandwidth at modern levels: the difference between 100Mb/s and 1Gb/s is only noticeable when doing bulk transfers.

All that being said... most of what we use our end-user computers for is wasteful overhead. Too many layers.

I agree, for me computers mostly became fast enough when SSDs became standard.

Same here. It was criminal how long Apple sold 5400rpm drives in macbooks.
