How to Buy a Desktop Computer

Whether you’re looking for a desktop computer that can handle graphics-heavy games or simple web surfing, Best Buy has a huge assortment of PCs that are perfect for your needs. We can even help you learn more and discover the right specs that suit you best.

What will you use your desktop for?

Desktop computers come in all shapes and abilities, from the everyday performer for basic computing to the digital workhorse for graphics-intensive gaming and video/photo editing. Some models are somewhere in-between, offering a range of connectivity options and the horsepower to keep you working and playing smoothly without any glitches.

Understand RAM, storage drive and graphics card

Before you decide on specific specs, it’s best to get a basic understanding of a desktop’s anatomy. The processor (CPU) is the brain, ranging from dual cores for everyday work and play to six or more cores, which can handle the demand without breaking a sweat. When you open apps, RAM (random access memory) allows the computer to access and interact with them, so the amount of memory determines how many apps can run simultaneously. The hard drive, either in hard disk drive (HDD) or solid state drive (SSD) format, stores your files and multimedia. Working in tandem with RAM is an integrated graphics card for media streaming or playing standard definition video. Dedicated video cards have the visual oomph to run power-hungry tasks like video editing.

Determine size

A great space-saving high performer is the all-in-one computer, usually a large monitor housing at least a dual-core processor and 4GB of RAM. If you want something eco-friendly with the ability to do basic tasks, a mini PC often features an energy-efficient Intel Atom dual-core CPU and as little as 1GB of RAM. The conventional desktop is a tower, a typically inexpensive and versatile machine that can do anything depending on the specs.

Operating systems (OS)

All desktop computers have operating systems to handle complex tasks, interact with users and keep up with system changes. The most common are Microsoft Windows OS and Apple Mac OS X. If you’re comfortable with working online, Google Chrome OS allows you to securely save files to a Google drive in the cloud while providing lightning-fast start-up speeds and media streaming capability.


1. Why would you want a desktop over a laptop?

While not as mobile as laptops, desktops can tackle more demanding tasks, with some models offering sleek, compact designs that look at home among modern décor. They’re upgradable and expandable so you can change or add components, such as RAM, to amp up performance. A small all-in-one computer can expand given the right ports, such as USB or HDMI, for connecting to external devices. Even at budget prices, desktops offer high performance and plenty of features.

2. What is the best desktop for a student?

Look for a desktop for everyday computing, enough to handle basic software applications, social networking or media streaming. Consider reasonably priced all-in-ones or mini PCs that fit your dorm room without looking like an eyesore. A mini PC offers storage that sits on the cloud, which can come in handy if your computer gets lost, stolen or damaged.

3. What’s new in desktop computers?

Desktops are turning into streamlined, space-saving machines while retaining their powerful performance. Microsoft Windows 8.1, for example, takes advantage of all-in-one desktops with touchscreens, allowing you to switch to the tile-based Windows 8 interface and boot directly to desktop mode. New processors, such as the 4th generation Intel Core processors, feature embedded security technologies to protect data from threats and malware that can penetrate software and the operating system.
