I have 16GB I7 10700kf 3070rtx.My display supports 240hz,i play in fullscreen mode and capping fps works for me,not remember gpu usage game at maintenance now,but i remember power consumption for 240hz was around 230-250 watt,for 120hz 140-160 watt.Game dropping fps in crowded areas,but that happens in every mmo when many players in one place.In Limsa i have around 80-90fps.
