My 7800xt pulls about 230 watts at full bore, giving me my monitor's refresh rate in FPS, 144. Limiting the framerate to 72 results in no tearing and drops the GPU watts to 170. Worth it.
Longevity. I build a computer once every 6-10 years and don't do much upgrading in between. Buying a beefier GPU means it'll play new games well for a good long while.
And it's not like I'm doing this all the time. I was curious about the power usage, so I made a script to monitor it and starting tinkering with settings to see what the delta would be. I'm a 100% ultra, max resolution 95% of the time.
