People that are simple enough to think that more VRAM is better regardless of anything else due to it being a bigger number will probably also bite the hook on the shaders being better due to having more.
Shader units are completely seperate from texture memory.
Texture memory is texture memory and unless you are using ATI's compression algorithm, once you run out thats it. Games with high res textures, high AA/AF and resolution will run over the 512MB mark. The GX2 was more than proof of this.
