video card fun

[AussieNightcrawler]

The amount of memory your graphics card has doesn't really effect performance, it just allows you to "have more stuff" at one time (which contradicts me, that could improve performance)

It does...

The more video memory the card has the better the performance, as the GPU (Graphics Processing Unit) is creating images of what you are seeing on screen, it needs somewhere to put them. This is where the memory comes into play, each pixel is stored in memory along with colour (color) and location on screen, also the memory is used as a buffer, completed images are stored here for later use.

So, the more memory the card has the better, in all honesty, if the amount of memory did not have any real performance benefits then 768MB and even 1GB cards would be a total waste producing.
