By:    Updated: February 7,2017

Ever since laptops became so cheap to own, many people have stopped buying desktop computers. However, there are some benefits to owning a desktop computer. When a computer gets old, most people will look for a new one to replace it, especially if it is a laptop. Desktop computers tend to be upgradeable, allowing you to swap or replace components without much effort. Desktop computers are also great for many uses, from homework to entertainment. If you have a computer with an HDMI port, you can play all your games and watch your HD movies on your HD TV, turning your computer into your media hub. There are many styles and designs for computers or laptops. Some manufacturers give you several different models to choose from, while others will allow you to customize them. The following criteria may help you:


All computers come with a processor (aka CPU, such as Intel Core i7 processor). The processor is the brain of the computer, running all operations and controlling everything you see. However, if you want stellar performance, you should look for a computer with a graphics card (Integrated graphics or Discrete graphics, the latter are better. If you want to play games or design, the latter are also better for you), although almost all computers allow you to add a graphics card after purchase. Lastly, all computers allow you to connect to the internet with a LAN cable, but it's easier to connect with a wireless networking card.

Memory and Storage

Many people associate memory with speed, and while RAM can speed up a computer, RAM is best used for heavy tasks like editing video , broadcasting a live stream, playing games, or designing (working on Photoshop or Illustrator). You can judge how well a computer will handle certain tasks by how much memory it has. A computer with 4GB of RAM will do well with work and media, while 16GB of RAM is great for editing video (as long as the rest of the components are fast enough for media production). Next, look for a computer with lots of storage space. All of the computers we looked at had a minimum of 1TB (the more space the better, the more rpm the better: 7200-rpm vs 5400-rpm, solid state disk better than mechanical hard disk), which can hold thousands of documents, songs and movies. This criterion may include Storage Space, Memory (GB), ...


One of the often-overlooked parts of a desktop is its physical design. However, if you have printers, keyboards, webcams or any other peripheral, you need to make sure your computer has plenty of USB 2.0 and 3.0 ports. Although memory cards aren't used as often, there are several tasks that need memory cards, including photography. Lastly, make sure you know what kind of monitor is compatible with the computer. Many computers are also compatible with televisions with an HDMI cable. This criterion may include USB 3.0, USB 2.0, Monitor, HDMI, Memory Card Reader, ...

Service and Support

The final aspect of the computer buying experience is the amount of supports (such as one to one service) that are available. Look for a computer with a long warranty, and make sure that there are options to buy a longer warranty. This criterion may include Warranty, Driver Download, ...
