Compared to computers of yesterday, today users look for more extreme action in their desktop computers. Graphic-heavy games, high-definition movies and videos, life-like role playing games, and virtual reality are popular nowadays and graphics cards make these things possible.
The onboard graphics that is on the motherboard is enough in doing most day to day computing activities. This integrated graphics card is enough already for internet browsing, word processing, and even watching movies. But when a user wants high-end graphics like 3D, this is the time that it needs a dedicated GPU. These cards have memory of its own and fast clock-speed processor in it.
Today peripherals come with built in TV tuner cards, high quality sound and 3D rendering. These cards provide dedicated video and gaming memory and has at least 1gb of RAM. A high-end GPU cannot guarantee top performance. The system unit that the card is installed should have a fast processor and have enough RAM for optimal performance.
GCA published an article and says that GPU use on the rise because of the demand of professional gaming. GPUs are power hungry and demand powerful processors, dedicated RAM.
The leading manufacturers of GPU and graphic cards are NVIDIA and AMD. Research and development on these companies are ongoing and have thrown several exciting inventions, like CUDA. It is a innovation that lets you run complex, demanding and resource- hungry software and applications on your PC.
The GPUs are connected to the motherboard and they are connected on what is called PCI interface. It was upgraded to PCI express a faster version in terms of transfer rates. GPUs need APIs like OpenGL or DirectX.
It is important to choose the right graphics card. Basically, you need to assess first the exact requirements and your usage before buying for a graphics card. A midrange card is enough for most users and can handle almost all graphic demands quite good.
To complete your setup, you need a sufficient power supply into, a fast processor, enough RAM and a high-resolution monitor for output.
