The Radeon Pro W6800, W7800 or W7900 would be the standard answer. A hacker-spirited alternative would be to purchase a used MI50, MI60 or MI100 and 3d print a fan adapter. There are versions of all of those cards with 32GB of VRAM and they can be found on ebay for between 350 USD and 1200 USD. Plus twenty bucks for a fan adapter and a fan.
Those old gfx906 or gfx908 cards are more competitive for fp64 than for low-precision AI workloads, but they have the memory and the price is right. I'm not sure I would recommend the hacker approach to the average user, but it is what I've done for some of the continuous integration servers I host for the Debian project.
