Historically buying additional VRAM has basically been worthless. Typically the way it works is that (a) most people buy the lower VRAM amount and (b) the games are written for the lower VRAM amount. But the other aspect here is the potential "future proofing" of the additional VRAM. This is also a questionable relationship because about the same time the VRAM is exceeded you also find so is the compute capabilities of the card. GPUs tend to be balanced, they come with enough VRAM to process games at a particular image quality but attempts to push past that usually degrade not just because VRAM is exceeded but also because the compute part of the GPU can't do it either. So in general buying more VRAM is always a swindle, it offers no benefit when its bought and rarely brings any benefit in the future. Not only that but they wildly overcharge you for it as well, its mostly for conning suckers out of money for higher margins.
