How to Upgrade Video Memory
Video memory is memory dedicated to graphics processing located on a video card. Some computers have integrated graphics cards, which means graphics processing is done by the motherboard using the system's RAM. Dedicated graphics cards are almost always much faster than integrated cards, so to upgrade video memory, it is best to buy and install a high-end, dedicated graphics card to replace whatever card you currently use. If you have a Macintosh, it is best to bring the computer to your local Apple store and request assistance from a Mac genius for video card upgrades and installation.

Tips & Warnings
The amount of total memory contained on a dedicated video card does not necessarily determine its quality. The speed of the graphics processing unit is often more important than the available memory. Check the website of your video card's manufacturer periodically for updated graphics drivers. Better drivers can improve performance significantly.
