Computer memory requirements: How much memory do you need?
When it comes to adding system memory, the general rule of thumb is the more, the better. On average, doubling the amount of memory in your system will give you ample "space" to work and will make an obvious difference in overall speed. This is especially with today's memory-hungry applications such as office programs, multimedia editing packages, and graphics-intensive games. More memory allows you to run more programs at once, and your favorite programs will be easier to use.
