What does a video card do? - JamesD What's the difference between having one and not having one? Good one vs. a bad on?

Best Answer: A video card is hardware inside your computer that processes the computer's visual output. Things such as the picture you see on your screen are probably produced by a video card. (Please Note: The first post is wrong, my XP desktop's video card is not working properly, but I can still see the picture on my screen). Games that are in 3D (They probably use DirectX to process their image) require a video card to supply you with the stunning 3D images. You can function without them using OpenGL (It's software on your computer rather then hardware), but I highly recommend having one. ATI and Nivida are good graphics card companies, but get ready, graphics cards are cheap! - FlashCreations

If you don't have video card your computers video is "onboard". It means the video is handled by the mother board in your PC, and not by a separate dedicated card. Onboard video has to share your system's main memory, while video cards have their own. You'll have much better performance with a video card. The only advantage of having onboard video is that it's cheaper. - G Note

You only need a video card if you want to have picture on your screen! - Safe Mode
