DLSS, FSR, XeSS, etc are all great for extending the life of older cards. Unfortunately, the GPU manufacturers found this out pretty early on and keep updating the technology to be more and more performance expensive, meaning you need a newer card to get any benefit.

Therefore no, the new versions are not really worth anything other than artificially boosting your framerate, which at that point just dropping the render resolution will probably give you more or less the same result.
