32GB at 2666MHz is overkill for most people

Probably not, unless you’re doing specific memory-heavy work like virtualization, large data analysis, or maybe heavy video editing with multiple applications.

Here’s the deal: RAM speed matters most for tasks where the CPU is waiting on data—gaming, for example. 2666MHz is already on the lower end for modern CPUs, so you’re leaving some performance on the table regardless of capacity. But if you’re not hitting the 16GB ceiling now, going to 32GB won’t make things faster; it’ll just sit there empty.
