A video card can be a very good way to upgrade performance of your existing desktop computer. When you purchase your PC from a retail shop or an online computer seller, it’s possible that your computer will only have an on-board graphics processor. Most of the assembled complete sets of computers are sold with on-board graphics processors.
So what’s an on-board graphics processor and what difference does a video card bring?
An on-board graphics processor is nothing but a small size chip. This chip shares its memory with the memory of your existing system. This chip is fitted on the motherboard. This graphics processor is considered several generations outdated when compared with the latest cards. If you are a graphic designer or love to play video games, your existing graphic card may not give you a satisfactory visual experience. You need to increase the speed with upgrading your card with a recent one.
Why do you need to upgrade your graphics card?
A graphic card allows you to off-load all graphics processing that your computer will have to perform in absence of a graphic card. These card performs the processing of all commands that present graphics or visual onto your computer system. This way it frees your computer processor to do other tasks. It comes with its own memory and it doesn’t share your computer’s memory. Moreover, a graphic card’s memory is faster than your computer’s memory and can perform your graphics related tasks with greater speed and with more efficiency. Thus, your computer’s memory doesn’t get involved in the graphic processing and you can do other tasks easily.
In the computer market, you will find dozens of brands of graphics cards. But most computer users worldwide rely upon two chip set manufacturers which are used in graphics cards. These companies are ATI and NVIDIA and they produce chip sets which are known as Graphics Processing Units (GPU). These GPUs are the most fundamental element of a graphics card. The popular brands using these chip sets are All-in-Wonder, GeForce, nForce, nVidia, Quadro and Radeon.
Before trying to buy a graphics card to make your PC more visually capable, you need to find out the type of graphical interface that your motherboard is using.
The three common types of graphics interface are
PCI-E.Majority of the computer motherboards have PCI slots. But a PCI interface is not considered very fast when compared with the other ones. So, it’s better if you have an AGP or a PCI-E slot in your computer motherboard. If your computer motherboard doesn’t have these two types of slots, you need to upgrade the motherboard first so that you can get a faster graphical processing speed. Your motherboard manufacturer will guide you to determine which type of slot you have for the graphics interface and whether existing slot can accommodate fast video cards. Then only you can replace your slower and older video cards with a new generation video card.
