I have a P4 2.0GHz, 512k secondary cache, 400FSB with 512meg of RDRAM PC800 memory. I have recently begun to play with digital photography with a 8meg camera and scanning of old 35mm color slides and building slide shows containing images and .mov files. Would bumping the memory to 1024meg result in a noticeable performance improvement or just be a waste of $200.00? It is a Dell 8200 and will not take any other type of memory.
