4k 60Hz is still largely unachievable for even top of the line cards when testing recent games with effects like raytracing turned up. For example, an RTX 4090 can run Cyberpunk 2077 at 4k at over 60fps with the Ray Tracing Low preset, but not any of the higher presets.

However, it's easy to get misled into thinking that 4k60 gaming is easily achieved by more mainstream hardware, because games these days are usually cheating by default using upscaling and frame interpolation to artificially inflate the reported resolution and frame rate without actually achieving the image quality that those numbers imply.

Gaming is still a class of workloads where the demand for more GPU performance is effectively unlimited, and there's no nearby threshold of "good enough" beyond which further quality improvements would be imperceptible to humans. It's not like audio where we've long since passed the limits of human perception.

4k@60 isn't all that good today and 5070 can do it with reduced graphics in modern games.

x90 cards IMO are either bought by people that absolutely need them (yay market segmentation) or simply because they can (affording is another story) and want to have the best of the latest.
