5080 Undervolting (I got great results) Has anyone else tried this?

I learned what undervolting is recently and i decided to give it a shot with my 5080. The results i got were actually incredible! i did not expect that level of performance increase.

TLDR: Undervolted to 90% and tweaked some settings on my 5080 using MSI Afterburner.
Before: 3DMark Steel Nomad score 8398
After: 3DMark Steel Nomad score 9027
Result: 7.2% performance increase while undervolting down to 90%

How?: I watched this video on YouTube. https://youtu.be/VyfD8I8yFts?si=WI2ZVRseN_Mtoehv and followed their guide until i found the right settings. (I am not comfortable explaining it fully in case i say something wrong. Here's the guide that i followed.
- I literally just googled a YouTube tutorial.

I'm just curious if anyone has tried doing this with their graphics cards and if they got similar results? Super curious if anyone got better results to me.

MSI Afterburner settings:
Clock mem (MHz): +500
Core (MHz) +150
Voltage Core (%) +0
Power Limit (%) 90
