The video card in your computer is what gives you the ability to game and be able to see things. The video card or graphics card is what produces images and lets you play all those games that you want to play all the time. It is what lets you watch videos and things like that. The video card that you need depends on what you use your computer for and what you are going to be using the video card for. If you are just going to be using your computer for business then you can usually use the stock video card, if you are going to be using your computer for gaming and watching a lot of videos then you should get a good video card like a Radeon or an Nvidia. When it does come time to replace your video card is sure that when you buy it or order it that you get the right interface, if your computer was made after 2000 then you most likely have pci express. AGP is the older type of interface and that is what I have on my gaming computer but it doesn't let me play games anymore so I had to buy a newer computer and now all my games work flawlessly. If you are a gamer get an Nvidia card. When you are just using your computer for normal things and typing and chatting you do not need an upgraded video card you just don't need it. You are just going to be typing and not watching any videos or playing games so you should be fine. People who are into digital and like to use the advantages of their video cards will need to get something that allows them to do whatever they need to do with their video card. Like use a crazy resolution and use two monitors to play their video games. If you are an editor then you are going to be using a computer and you are going to be watching a lot of videos so therefore you will need an upgraded video card so you can watch the video on one screen and edit the video on the other screen, with a stock video card you cannot perform dual screen that well. You can even add a TV instead of just having another screen but it is much easier just to add a second screen so you can just slide your mouse to the other screen and start editing.

So if you need a video card for the job that you have then you need to go out there and look for one that you need. If you are a big time gamer then you might want to get a SLi ready motherboard so that you can run two video cards instead of one at the same time. You will be using twice the power so your picture will be like plasma.
