Peripheral marketing sells aesthetics. Performance comes from a short list of physical properties, and most of them cost very little.
What measurably helps
- Mouse weight and shape: fit matters more than sensor specifications.
- Desk height and chair: the largest single factor in long-session accuracy.
- Monitor stand: correct eye level reduces fatigue more than a faster panel.
- Wired connection: removes a variable that wireless occasionally introduces.
What rarely helps
Higher DPI than you use, RGB lighting, and extra buttons you never bind. A lighter mouse with two side buttons outperforms a heavy one with twelve.
Where to spend
Spend on the contact points: mouse, keyboard switches, and the surface they sit on. These are the parts your hands interact with thousands of times an hour.
The upgrade order
Chair, monitor height, mouse, keyboard, then everything else. Buying in that order produces a bigger improvement than any flagship device.
Bottom line: the best peripheral purchase is usually furniture, and nobody markets it to gamers.
