VRAM (video memory) has two primary functions: frame buffer and  
texture cache.  The frame buffer is what you see on the screen.  The  
texture cache is used to cache textures for 3D models.  Larger texture  
cache means less time spent hitting disk to load textures.  You're not  
loading textures so more VRAM won't help.
