The PCs we can buy in the big electronics stores and supermarkets are incredibly comfortable. They plug into an outlet, turn on and can be used immediately. However, this incredibility is paid for at a decidedly higher price than the value of the components used in them and with unavoidable compromises in terms of performance. It is difficult to find a pre-assembled PC with a large amount of RAM, a good processor and a powerful video card: something is always missing.
Therefore, it might be a good idea to study and build a computer using hardware Custom Build Wizard sites. This way, you can get a “perfect”, uncompromising PC that is completely in line with your needs and can guarantee much better performance than pre-assembled ones that can be purchased at the same price.
Processor:-
Processor is the heart of the computer, the one that actually performs the calculations. Its power is expressed in GHz and can have two or more cores, i.e. two or more physical processors that allow it to have more computing power without increasing the clock. It comes complete with a radiator, a kind of “plate” that is applied to the processor to dissipate the heat generated by the processor and thus prevent overheating.
Heat sinks can be airborne, passive or liquid. The former are connected to one or more fans to dissipate heat. The latter do not require the use of fans (therefore, they are suitable for fewer processors while liquids use an external radiator and small internal pipes to cool the processor using a special liquid.
Video Card:-
It’s a component of fundamental importance for all those who need to use the PC to play or work with graphics. Other parameters to consider before purchasing include the amount of memory included, i.e. memory dedicated to games and graphics applications (separate from the RAM that will be installed on the motherboard), the frequency and types of video outputs supported for example, HDMI, DVI, and VGA). It is also a good idea to check if the PCI slots on the system board are compatible with the “connections” on the purchased video card.
Sound Card:-
Sound cards built into motherboards are now more than enough for listening to Music, watching movies, and playing games. If you have professional needs related to the audio industry, the discussion is changing, in which case you need to buy an external sound card that is compatible with your needs.
RAM:-
The memory in which the data of the used applications are temporarily stored is known as RAM. It can be DDR, DDR2, DDR3 or DDR4 and each type of memory has a different type of motherboard slot (so before you buy it, make sure the two components are compatible with each other). The higher the amount of RAM installed in the PC, the better the system’s ability to manage multiple applications simultaneously or run more sophisticated software (for example, professional graphics, next-generation video games, etc). Another very important parameter to consider is the frequency of memory, i.e. the speed with which RAM transfers data. For more information, you can read our guide on How to Choose RAM.
