It's not the memory of the graphics card that's the problem. It's the GPU chip itself. The Radeon HD2400 is pretty weak. If your Radeon HD2400 had 2GB of memory, it wouldn't perform any faster, at all. Don't make your decision based on a graphics card's memory. Base it off the GPU itself. That's what makes your performance better. Memory amount only matters if you have too little. In fact, memory speed is more important for a GPU (for the main system RAM, it's often the opposite, where more amounts is generally better than more speed).
