VRAM is extremely important for futureproofing though. I remember back in the day when I had to replace my GTX 690 because it didn't have enough VRAM and all the new games stuttered like crazy on it and were practically unplayable.

Same happened to me with my GTX 780 Ti with its 3GB of VRAM. Killed especially VR experience when always 3-4 GB were stored in the shared memory, the GPU itself ran at about 30 % load because it wasn't getting textures fast enough...
