ASUS already has a XG259QN 24.5" HDR 380 Hz gaming monitor so we'll have to look more closely at the specifications to see what's new with the QNS model.
Those who need a monitor with this refresh rate know who they are. For most of us, it's overkill. And if gaming isn't your priority then you can definitely do better. This is a 1080p monitor after all.
