idk the radeon vii does just fine. You can get a used 2080 for what $500 while the vii still sells for $600+. Even the 2080 S probably won't retain the same value as the Radeon Vii in a years time. So if you bought the 2080 your out $200. While the vii has only dropped like $50. Compute units etc.
I'd buy a used 1080 ti for about $400
