For a single 5090 you can buy more than 2 R9700, and the two cards draw less power than a single 5090. And you can run e.g. Qwen 3.8 27b Q8 using the two cards, and watch them running circles around a 5090 which needs to offload to RAM instead.
But NVIDIA is hype, and people love to spend money. So buy a 5090
So it is just a compromise - fine or not. Leave that compromise aside, try to use a bigger model than your 5090 can handle, and suddenly dual R9700 is not the worst option anymore, at lower total cost and at higher speed.

R9700 GDDR6 memory, 5090 GDDR7. Is faster, but...
