For general system performance, every GTX card will have an improvement.
But for quality, mostly only RTX card will have that. Asside for some improved tunable features.

The Turing chip (GTX/RTX 20x0) brings a new nvenc revision that will encode with a quality between fast and medium preset of x264, this is what your picture says. Since a perceived visual difference between this and slower presets is not recognizable, there is no reason to not encode with nvenc if you have a GPU with a Turing chip.

The older chips such as Pascal (GTX 10x0) encode with a quality that is about as good as the veryfast preset of x264. This is one quality level below. You are able to perceive a difference between this and better presets, but the quality is still not bad. In terms of perceived quality, it's better to use this encoder and have no lags/skipped frames than it is to use x264 with a better preset but have skipped frames due to the high cpu usage.

It seems quite some people prefer seeing a choppy video up to a slideshow with perfect visual quality each frame instead of not so perfect visual quality but a smooth stream, but I don't understand why someone will prefer it this way. A smooth stream is much more preferable than the pure encoding quality of the pictures.
