And people that render/compute/train. Workstations are still a big market for high end GPUs.

The 30XX series were generally overpriced but being able to NVLink two 3090s for 48gb vram was such a good value proposition for GPU rendering that I immediately bought two.

Now 4090s are double the performance of a 3090 but Nvidia removed NVLink for consumer cards and I can't talk myself into upgrading, even for professional use. Nvidia's really been going on a greedy warpath lately. Let's hope the 50XX series head back in the right direction although I heavily doubt it.
