The card manufacturers will just release a BIOS update that will limit the power usage, so the filtering capacitors won't see so much noise. I'll wait and see if the 3090s have any similar issues. The 3070s are going to be the best buy for most people anyway. I've already got a new system going together, but it won't be a 3080 I put in it. I don't see anyone changing their layouts with an improved filtering scheme. The BIOS approach is just cheaper.
