Running an undervolt on both my 14700K, and Gigabyte 4080, and the temp on both after a slight underclock is amazing! Running at 1440p Max Settings, DLSS set to Quality, and Frame Gen turned on, neither CPU & GPU go above 60c. I know the 4080 is a well-equipped card when it comes to out of the box temps, but with a slight underclock the temps are great, with no performance loss that I can notice! 3d Time Spy score was around the 27,000 range. (I know this is an Overclocking sub reddit, but I've seen undervolt stuff here as well so figured I'd post my results lol)
