A graphics card is an integral part of the motherboard that creates an output image to the screen. Commonly, these are marketed as dedicated or discrete graphics cards, stressing the difference between these and integrated graphics cards. Integrated graphics cards utilize the power supplied to it by the mother board and is found in notebook computers. The laptop's operating system, on the other hand, uses the graphics card directly. While the former is more popular because of its lower cost, the latter provides better graphic capabilities for the same price. It also saves on energy consumption.
Dedicated graphics card, as the name implies, is reserved for the exclusive use of graphics processing unit (CPU). If you want better and faster graphics performance, the dedicated card is the way to go. However, buying a dedicated card comes with a price. That price is higher than that of an average home computer or laptop and requires more resources from the processor.
Another thing to consider when purchasing a video card and a display card is the RAM. RAM is the most significant component of the graphics processing unit. The processor can access the information from the video card, but the ram is needed for constant processing of information from the display card. Both are essential for computing. In a notebook, the display card alone consumes about 95 MB of ram. As for the graphics card, it may consume more than twice that amount for constant computing.
A good graphics card will make your computing experience more pleasurable. With good graphical capabilities, you will definitely enjoy a better user interface. This means faster and interactive gaming, better color rendering, and better visual effects. If you have a good motherboard and a good graphics card, then you should have no trouble enjoying your computing experience.
The two major graphics cards available today are the ATI Rage, and the Nvidia PhysX. The ATI Rage is the old school, and it is still capable of great performance. However, it is quite outdated now that the new generation of gpu's has evolved. The Nvidia PhysX however is the modern-day of graphics cards under 5000.
There are many factors you need to consider when purchasing a graphics card and a CPU. You should first determine how much processing power you will need from your system. Graphics cards come in a variety of watts, and the more processing power you need, the more bucks you have to spend on it.
Next is the kind of processor your motherboard has. Most of the time, a good graphics card needs to work well with an integrated graphics processor (IGP). Integrated graphics processors come with their own separate components such as the hard drive, and the memory controller. If you are getting a motherboard that does not have these parts, then look for an IGP along with a powerful processor. If you can find a motherboard that is made by a top brand, then it should definitely be able to support a good graphics card.
Last, is the expansion slots of your motherboard. Some motherboards do not have any expansion slots, so they cannot support graphics cards. On the other hand, most of the motherboards today have at least 3 PCI Express expansion slots. If you can find a motherboard that has all three PCI express expansion slots, then you will have the ability to use both your graphics card and the hard drive. Look for a motherboard that has PCI Express slots, so you can use both the hard drive and the card.
The last two things to look out for in a motherboard are the PCI Express slot size and the AGP bus speed. You might notice that these two are very close to each other on many motherboards, but that is not necessarily a good thing. The PCI Express bus speed is what actually transfers the graphics card's data from the host PC to your graphics card. The bus speed also determines how quickly the graphics cards can work with your computer. The smaller the bus speed, the better the graphics cards will be able to work.
The faster the mhz, the better the graphics cards will be able to run. The average man for a graphics card with a processor on it is roughly 4500 RPM. There are some older motherboards that have a lower mhz, but those aren't as popular as the new systems. The newest i7 have a maximum mhz that is about 7 Billion rpm. This should give you plenty of room to get the best performance out of your CPU and motherboard when it comes to using your graphics cards.
As you can see, your motherboard and video card are very important to your processor. You will need to make sure that both are functioning properly before you go out and buy a new system with both. When purchasing a video card or an old one, be sure to check the speeds and the voltage level, both of which affect the performance of your graphics components. If you find that your motherboard or the video card is not working right, then you will be able to easily troubleshoot the problem and get it running correctly again.
