Buying a system unit for a PC is a very important task, because the choice depends on how effectively and for a long time the computer will serve you. The system unit is equipped with many components, the characteristics of which should be carefully studied in order to make the right choice.
The purpose of this article is to help the buyer navigate the types of computer assemblies and the characteristics of components. Having this information, it will be easier to choose a PC option for the implementation of certain tasks (working with documents, watching movies, playing games, etc.
There are three types of PCs, depending on the purpose:
When choosing a system unit for a gaming computer, you should take into account that the gaming industry is developing at a rapid pace, so in order to enjoy a comfortable game, you need to select components that meet the latest system requirements. Modern gaming computer configurations cost a lot, but at the same time they will provide the most realistic picture, exclude system braking and frame breaks. In addition, a gaming PC can handle tasks such as video editing, working with graphic editors, etc. without any problems.
Such computers belong to the middle price segment. They will provide comfortable listening to music and watching videos, as well as using any Internet resources. This PC can also play some non-demanding games.
To optimize your PC for your needs, consider the following:
Admirers of VR technologies should take care that the video card supports the corresponding devices.
For a PC to play multichannel audio, it must have a built-in audio interface. In extreme cases, good sound can be provided through an audio chip built into the motherboard that supports a 5.1 or 7.1 speaker system, which will be quite enough for a home party.
PC for office, study or work from home
An assembly that has a low cost, but at the same time is capable of effectively solving problems such as: working with text editors, accounting and business management, using e-mail and other Internet resources. Supports such a PC and IP telephony, and Skype. With it, you can watch videos or chat on social networks and even play the simplest games.
The most important parameters when choosing a motherboard are:
The number of slots for connecting RAM. There should be at least 2 of them, since higher performance can be achieved by dividing the RAM into two strips (for example, 2 strips of 4 GB instead of one for 8 GB). In addition, the additional slot will come in handy in case of upgrading the PC configuration.
Overclocking support (important for gaming PCs equipped with the appropriate processor).
As for the design of the board, equipping it with backlighting and other bells and whistles, everyone decides the need for them individually, it should only be borne in mind that all these additions affect the cost of the board itself and the system unit as a whole.
The choice of the processor must be carried out according to the purpose of the computer:
For an office PC, a quad-core processor is sufficient. A more simplified version is a dual-core processor with 4 or more threads. It can be used if you do not intend to work in Photoshop and other demanding programs. For example, an 8th Gen Intel i3 4-core processor will provide the same performance as a Koby Lake i5 family.
For the system unit of a home multimedia PC, almost any 4-core processor is suitable, it is desirable only that there is a sufficiently high clock frequency.
Higher requirements for the processor of a gaming PC, as modern games require a fairly high power. For gaming computers, it is better to install a processor with 6 or even 8 cores, which will provide a margin of power for new games. A CPU with an unlocked multiplier will come in very handy here, i.e. for overclocking, providing a significant increase in performance (in AMD processors, overclocking is indicated by the letter “X”, in Intel processors – by the letter “K”).
Modern AMD processors (RYZEN 5 or 7) or 8th Gen Intel Core i5, i7 provide excellent performance even at factory settings.
If the system unit is completed for an office PC, then there is no need to install a discrete video card. It will be enough to be integrated into the processor. This option can satisfy the assembly of a multimedia configuration. But if you still choose a discrete graphics editor, you will get the opportunity to use glasses or a virtual reality headset, although this will have to overpay a little. In this case, you need to check if the VR technology is supported by the device.
The best option for gaming computers is the GeForce GTX graphics card (from the 1060 generation), which is ready for serious tasks at an affordable cost, especially if it is designed for 6 GB of memory. Among the cheaper options, you can choose the Radeon rx570 (4 GB).
The most important characteristic of RAM is its size:
for an office computer there is enough RAM with a capacity of 4–8 GB;
for multimedia, it is recommended to have at least 8 GB of RAM, as a last resort, you can install a 4 GB card with the prospect of adding in the future;
in gaming PCs, 8 GB is the minimum allowable volume, but it is better to immediately install RAM to 16 GB, which will provide the maximum amount of the game.
The frequency of RAM for office and multimedia PCs does not really matter, but in gaming computers, the frequency affects performance, and its value should be at least 2666 MHz
