Couple of questions :)

Hi all not been on for a number of years and well out of touch with everything pc.
I have a 6900xt with terrible coil whine under load/playing games and looking to change, not the ideal time I know what would be a upgrade ? 4070ti 4080 (would like to go back nvidia tbh), I also have a 850w power supply in my pre-build from OCUK is this enough for 40xx card?
Thanks in advance

you could be replacing the 69 with a new GPU for it to whine just the same.

I didn't think of that how would I go about finding the culprit ?

6900xt is Radeon Toxic air cooled and psu is a 850w 80+ bronze don't know what make unless I take it out (not happening)
