looks like nvidia 3080 is pretty good but a power hog.

mine do 94 and 91

or 185 at 530 watts measured on the wall with a kwatt meter.

i have some four card amd 5600 that do about 168 mh at 460 watts.

so nvidia 3080 is a bit more power hungry but uses less space

the 6800 xt uses less power

and the 5700xt and 5600 xt are still okay.
