What Things to Know Before Buying a Computer Online?

Today, probably, there are no such people who do not have a home computer. Moreover, many have a computer in each room, and have a working laptop. However, it is far from a secret that technology is improving every day, and computers are no exception. You can, of course, update some parts, but over time you will have to change the entire computer.

Things To Check Before Getting a New PC 


The main processor brands are Intel and AMD. The processor of an average computer has 4 cores, the frequency of each core is 3 GHz. There are also some processor families – Intel Celeron, Intel Pentium, Intel Core 2 Duo, Intel Core i7, AMD Athlon, AMD Phenom, etc. AMD processors have always cost less than Intel processors, while not differing in quality. 


The next step is to pay attention to RAM. A more modern type of memory is DDR 3. RAM can be 2 GB, 4 GB, 8 GB, etc. The price of the purchased computer will also depend on the amount of RAM. Do not forget that 4 memory sticks can be installed in the computer, i.e. you can add RAM to your PC at any time. 

Video card

Next, we look at what video card is in the computer. It can be built-in or discrete. It is better if the video card is discrete, because it has better performance. The most popular graphics cards are GeForoe and Radeon, and Intel HD has also become popular recently. Moreover, a computer with an Intel processor will have a GeForce or Intel HD video card, and a computer with an AMD will have a Radeon. For an average inexpensive computer, a card with 1 GB of video memory is quite suitable. 

Hard disk

Next, you can check which hard drive is installed, more precisely, how much memory is in it. On average, a 500 or 750 GB hard drive is installed in monoblocks. However, even if you have a 250 GB hard drive, in the future you can always make up for the lack of free space by purchasing an additional HDD drive.
Power supply, motherboard, DVD drive

Also, when choosing a system unit, you should pay attention to the power of the power supply, the presence of a sound and network card – they are usually integrated into the motherboard as standard. The selected processor must be compatible with the installed motherboard. Almost all configurations have a DVD-RW drive. 

Monitor and optional accessories

Having chosen the candy bar that suits you best, you can start choosing a monitor. Here you should pay attention to the diagonal, the connection interface and the type of display. The type of display can be LED – (OLED) or LCD (TFT] LED – the technology was invented relatively recently. In fact, it is the same TFT monitor, but with a changed backlight. The diagonal of the display can be from 15 to 25 inches or more, here the choice is yours, it all depends on what kind of monitor you need, and how much money is left after choosing a system unit. Interfaces for monitors are usually VGA, DVI, HDMI. In more expensive models, there may be a USB interface. When buying a computer, do not forget about the keyboard and a mouse, you can take a webcam and an uninterruptible power supply.
