Actually it's not VRAM anymore, but whatever you call the memory 
dedicated to the GPU.

It is cheap to put 8 GB of RAM into a computer, but graphics cards with 
more than 1 GB memory are expensive and uncommon on e.g. laptops. And 
this memory will be needed for other things as well, e.g. graphics.
