6GB with "The right mods"? Don't you mean "a mish-mash of conflicting and abominably under-optimised mods made by amateurs who weren't talking to each other"? Because if those things were properly managed and synchronised, they would probably take up about half that spaceEven with one 1600 monitor, the right mods can bring current 6G cards to their knees in terms of memory on the card used. However those examples are extremely few right now. So there is a need for it, but a niche. Plus then modded other resolutions, 2-3 monitor setups, etc. More memory is not a bad thing in any regard accept cost.
sorry but how does bigger/higher resolution textures and meshes with more polygons (to make things smoother) get optimised? make the textures smaller and less polygons? defeats the entire point of it
