I have a rather stupid question about the MB in graphics cards.Im buying a laptop with a 8400mm 128MB graphics card and i want to know if the memory works the same way as RAM,do you only use it when playing a game or when you install a game is a certain amount of space taken.

It's texture memory. It's only used when the graphics adaptor is rendering an image. You're confusing GPU memory, RAM and hard drive space.

Ugh.

You're getting mixed up. The memory on the graphics card is only ever in use whilst it's rendering an image - say, when you're playing a game, or if you have Aero (the snazzy desktop effects) enabled in Windows Vista. Installing a game will have absolutely no effect on it.

^ That is about as simple as you can put it.

That's pretty impressive; I don't think I could manage to dumb it down that much. :p

Generally Laptops graphics cards have dedicated Video Memory (sometimes called VRAM) and sometimes contain Shared Memory which is often advertised on laptops. Dedicated memory is used exclusively for Video Applications while shared memory is memory drawn from CPU and System RAM to power video applications. Dedicated memory is better for gaming as the VRAM is used exclusively for generating the graphics while shared memory means that if your running a game the CPU, RAM are competing for video memory thus slowing the game down. I'd assume the model your buying contains 128 MB dedicated memory which will be sufficient for most games.

It's commonly referred to as frame buffer memory. Think of it as a VRAM cache for storing graphics rendering data to keep the game running smoothly rather than skipping frames at times when lots of computation intense graphics are being displayed. It's a lot like capacitors store energy for high watt bass frequencies in audio systems. The higher the VRAM capacity the more texture intense games you can run and at higher resolutions.
