So at least up until this point 6GB VRAM hasn’t been an issue. The previous king of this title would have been the GeForce GTX 980 Ti, and so far the Maxwell part has aged very well.

The RTX 2060 offers performance similar to the GTX 1070 Ti, but that card packs an 8GB memory buffer, as did its non-Ti counterpart. Today we're investigating claims that the new GeForce RTX 2060 is not a good buy because it only features 6GB VRAM capacity.
