Choosing a computer correctly
Some people prefer to buy already-equipped models in stores, thinking that the specialists in them have already thought out all the nuances in advance. In fact, this is not always the case. After the purchase and the start of use, the consumer may find that this technique does not meet its individual requirements. In addition, it may happen that after a while the programs or components of the computer simply fail.
In the price lists of finished computers, usually only their main characteristics are given: the type and frequency of the processor, RAM, hard disk and video card. Often there is no information about the component manufacturer, sometimes only the processor characteristics are indicated, and the numbers in the price list about the motherboard, case and power supply will not tell much to people who are not very knowledgeable.
In order for a computer to meet your basic requirements, you first need to decide whether a machine for games, business work or something else will be bought. A personal computer for office work may have more modest parameters, and the following powerful components are already needed for games: a processor, a video card, RAM and a 450-500 W power supply. Computer games take up a lot of space on your hard drive, and in order to get real pleasure from your favorite games, you need high quality and monitor resolution. So, it is worth stopping at a complete set of the computer in more detail.
RAM. The greater its value, the faster all programs will load. Information is already written to the system module, so the hard drive does not always have to be accessed. For the system, RAM is needed a little, but for the game it will require a sufficiently large amount of it. At present, 512 and 1024 MB may not be enough, so try to buy a computer with maximum memory values of 4-6 GB.
Video card The memory of a video card is measured in MB similarly to RAM. For work in the office, even a video card built into the motherboard with low performance and a small amount of memory is suitable. But for complex actions, you need a video card with powerful indicators. Today, there are many manufacturers and types of video cards, so before buying an unknown brand, you should first find out its graphic characteristics on sites such as IXBT or 3Dnews or any other.
HDD. What matters more here is not its volume, but speed. A large hard drive will allow you to store a large amount of information you need, and if you have a high-speed HD disk, the data will be processed much faster, since they have a fairly high recording speed. For high computer performance, you need not only a good processor, but also a high-speed hard drive.
Monitor. It is one of the most important components of your PC, because you perceive all the information directly through the monitor. Also, your safety will depend on its quality, because often many people have to spend more than 8 hours a day at the computer. For an excellent image, you should buy a monitor with a diagonal of at least 17 inches. The Hz monitor indicators (determine the frequency) also play an important role in the image, the more there are, the better. Today, stores offer to purchase TFT or LCD type liquid crystal monitors. Electron beam tube computer screens are a thing of the past. Any monitor must comply with established safety standards. For games and entertainment, it is recommended to choose LCD monitors with a high matrix response speed and a wide viewing angle for comfortable viewing. Make sure the monitor is free of noise and wave distortion.
In addition to the monitor and the system unit, you must also choose the right keyboard, mouse and speakers. The keyboard is either gaming or standard for easy typing. It is advisable to choose speakers with output 5 and 1 for a home theater. When buying a wireless mouse or keyboard, do not forget about the need for their power source.
Choosing and buying a personal computer is not an easy and responsible process. All components of the computer must be purchased in high quality in reliable stores with a good reputation, then your iron friend will not cause you any trouble and will last a long time!
