I've read elsewhere that DLSS 2.0 will now finally use the tensor cores and not the regular shaders dragging FPS down. That alone should improve performance a lot on both the old RTX 2xxx and the new 3xxx. For me the 3xxx might be the first upgrade I'm interested again. When the GTX 1xxx series was released, tri-SLI on my GTX 980ti was still alive and well. Two 1080ti wouldn't have been much better. When tri-SLI scaling was eliminated in the driver and when one of my 980 died, the 1xxx series was already end of life, and the 2xxx way overpriced.
