Memory is the kind of thing where you either have 'enough for the tasks at hand', in which case everything runs 100% normally.

Or you do NOT have enough for the tasks at hand ... in which case performance will tank significantly (though less so if you have an SSD because that's where the 'overflow' from the physical RAM would go, known as your swap file, among other names).

There's absolutely zero gain to having more RAM ... than what you actually need for whatever you're doing.

And Windows is pretty good about unloading programs from physical RAM that you're not currently using (but that started up since your last system restart) if you start to get low.

Biggest single improvement you can make as stated above is going from a spinning HD to an SSD, i.e. that's the biggest gain for the most common tasks.

However depending on what you're doing, a faster CPU and/or video card can also make big differences. Relatively heavy duty programs like Photoshop and Lightroom could potentially benefit from such upgrades.
