I was looking to buy a new low powered graphics card, which was offered with two memory amounts, 256 and 512. I have heard however that sometimes it isn't worth going for the larger memory amount as it is rarly used.
Is there any truth in this, and if so, what are the factors that don't make it worth going for the card with the larger worth it? (What other specs of the card mean that the additional memory can't be used)
