Graphics Card Guide
You have some catching up to do if you do not know what a graphics card means. The graphics card is an onboard card inside the PC. It is attached to the motherboard and has a port accessible on the back of the PC case to which a cable from the monitor is also connected.
What does a graphics card determine?
A graphics card determines the quality of images on your computer screen.
Resolution: It means the density of pixels on your screen. This would determine the clarity of the image. The higher the density, the higher the clarity.
Number of colours: The quality of images depends on the number of colours a graphics card can deliver.
Frequency: The flickering action of your screen can be reduced or controlled by a good graphics card.
Speed: The speed at which graphics get updated on your screen is also a function of the graphics card.
What determines the performance of a graphics card?
Memory Capacity: The size of the memory would determine the resolution and number of colours a graphics card can attain. A graphics card with a memory of 16 MB or more can deliver as many colours and pixels as your monitor can accommodate. However, a graphics card of say, 4 MB would tell you the difference between superior and not-so-good images.
Speed: The speed of the graphics card decided how fast the images are updated on your computer screen.
When should I update my graphics card?
You know a graphics card needs updating when:
The animation is slow and uneven when you are playing those sci-fi computer games.
The images take forever to update and your profession (or interest) involves a lot of image processing.
The quality of images on your screen is nowhere near, what you desire.
Nevertheless, updating the graphics card does not solve all PC problems and be very cautious before going for one.
Tip: Get a graphics card that offers the highest resolution, speed and number of colours.
