I am thinking of purchasing an AGP video card for my AMD-K6-II processor (400mHz). I was not sure how much memory would be suitable for my use. Can someone categorize what each type of AGP card (4mb, 8mb, 16mb, 32mb) is useful for. I want to use this computer for word processing and occasional video graphics use downloaded/streamed from the internet. Also for some of the higher end AGP cards, there is a mention that it can stream DVD video. does that mean that my cdrom can use the DVD cd and play it on my computer without a dvd player.
