Reasonable question that comes up often enough to deserve a thread. The tuning culture that exists around gaming hardware optimises for peak framerate in a short window on a machine the owner can reinstall at will.
A workstation has different constraints. It has to stay supportable, it frequently has to satisfy a security posture the owner does not control, it runs sustained rather than bursty work, and the cost of an unexplained instability is somebody's working day rather than a lost match.
That difference changes which tuning is worth doing. Most of it turns out to be removing unnecessary work rather than raising limits.
