Sorry not really interested in 6800xt vs 3080. I haven't bought an NV GPU since Geforce3 ti500 if you ignore a gt1030 I bought at some point for a media pc then never used it. I was more interested in cpu scaling between similar performing cpu's of differing core counts but where overall performance is roughly the same.
fwiw I will probably buy the 6900xt in the new year and if they don't fix some of the workstation type performance issues ill be using it alongside my radeon 7.
