Changes

When you buy a new graphics card, remember there are many different types of interfaces including PCI, AGP and PCI Express. You need to buy a graphics card that your motherboard will support. Many old PCs use PCI and some fairly new ones use AGP but most brand new PCs now use [[:wikipedia:PCI Express|PCI Express]]. Don't get muddled up with PCI and PCI Express - they are not compatible. Be careful that the person who is selling the graphics card knows the difference between them - you don't want to buy a graphics card that is not compatible with your PC! Also remember that you will need a graphics card with the right output for your monitor. Most graphics cards and monitors use VGA but some newer models now use DVI. There are many different types of DVI and they should all be compatible with each other. DVI gives a better quality picture than VGA, so if you are looking for a graphics card/monitor, try to buy ones that support DVI.
