How to Buy a Desktop Computer
Whether you're searching for a desktop computer that can handle graphics-heavy games, creative projects, or everyday tasks like web browsing and streaming, Best Buy Canada offers a wide selection of Windows PCs and Apple Macs to fit your needs. We'll help you understand the key specs and features to look for, so you can find the right desktop to match your lifestyle and budget.
What Will You Use Your Desktop For?
Desktop computers come in many forms, from everyday performers built for simple tasks to powerful systems designed for gaming, video editing, and 3D design. Some models are built to handle a bit of everything, offering fast processors, strong connectivity options, and enough storage to manage work, entertainment, and multitasking with ease. If you prefer a sleek, space-saving option, all-in-one desktops like Apple’s iMac or Windows-based models combine the monitor and computer into one stylish unit, making them a great choice for home offices and creative workspaces.
Understanding RAM, Storage, and Graphics Cards
Knowing the basics of a desktop's key components can make it easier to choose the right model. The processor, or CPU, acts as the brain of the system, handling everything from simple tasks to complex programs. Modern multi-core processors such as Intel Core and Core Ultra, AMD Ryzen, and Apple silicon deliver strong performance and efficiency across a range of workloads. Select newer processors also include dedicated AI acceleration for supported applications and features.
RAM (random access memory) helps your computer run multiple apps smoothly; more memory generally allows for better multitasking. Storage drives come in two main types: traditional hard disk drives (HDDs) and faster solid-state drives (SSDs), which help your computer boot up and load files quickly. SSDs are now common as the primary storage option in modern desktops, while HDDs can still be useful for additional high-capacity storage.
Graphics cards handle video and visual performance, with integrated options ideal for everyday use and dedicated cards offering the power needed for gaming, 3D rendering, video production, AI-assisted creative workloads, and other graphics-intensive software.
Choosing the Right Size
Desktops come in several sizes and form factors. All-in-one computers combine a large screen with internal components, making them perfect for clean, clutter-free setups. Mini PCs and compact desktops like the Mac mini offer great performance in a small, energy-efficient package that fits almost anywhere.
Traditional tower desktops generally provide the most versatility, allowing you to customize and upgrade components like graphics cards, memory, and storage as your needs evolve. Upgradeability varies by model, however, and compact desktops and all-in-one systems may offer fewer user-replaceable components. Whether you need a minimal footprint or room for expansion, there’s a desktop size that fits your space.
Understanding Operating Systems
Every desktop runs on an operating system (OS), which manages software, files, and system settings. The two most common options are Microsoft Windows and Apple macOS.
Windows 11 powers the latest Windows desktops, offering a streamlined user experience, smarter multitasking tools, and enhanced security features. With support for Windows 10 having ended in October 2025, Windows 11 is now especially relevant for shoppers replacing an older PC.
Apple’s macOS provides a clean, intuitive environment with close integration across Mac, iPhone, iPad, and other Apple devices.
Some compact desktop systems also run ChromeOS, which focuses on web-based apps, cloud services, and a simple, security-focused experience. ChromeOS desktops are less common than Windows PCs and Macs but can suit users with primarily web-based needs.
FAQs
Why Choose a Desktop Over a Laptop?
While laptops offer portability, desktops can deliver strong performance, flexible configurations, and good value for the hardware you get. Traditional tower desktops often provide better upgrade options than laptops, allowing components such as RAM, storage, or graphics cards to be replaced or expanded over time.
Many modern desktops also come in sleek, compact designs that blend into almost any space. Keep in mind that upgradeability varies by form factor, with mini PCs and all-in-one computers often offering fewer expansion options than full-size towers.
Even budget desktops can offer strong processing power and multiple connectivity options, making them a smart choice for work, creativity, or family use.
What Is the Best Desktop for a Student?
For students, a reliable desktop that can handle everyday tasks like word processing, research, video streaming, and social networking is ideal. Compact all-in-ones and mini PCs are great options for dorm rooms or shared spaces, offering enough power without taking up too much room.
Choosing a desktop with cloud backup or cloud-syncing services can also help protect important files and assignments and make them easier to access from other devices.
What’s New in Desktop Computers?
Today’s desktop computers are faster, smarter, and more connected than ever. Equipped with modern Intel Core and Core Ultra, AMD Ryzen, and Apple silicon processors, current desktops deliver impressive speed and energy efficiency. Select newer Windows desktops also include processors with dedicated neural processing units (NPUs) for supported AI-powered features and applications.
Windows 11 desktops are optimized for better multitasking, gaming, and creative workflows, while macOS devices continue to offer strong integration with creative apps, productivity tools, and the broader Apple ecosystem.
High-speed wireless connectivity such as Wi-Fi 6E and Wi-Fi 7 is increasingly available on newer systems, while USB-C, USB4, and Thunderbolt are offered on many modern desktops depending on the model.
Modern operating systems and hardware can also include features such as device encryption, Secure Boot, biometric authentication, and hardware-backed security, depending on the desktop and configuration.
Faster SSDs are now common, dramatically improving startup times and file access, and modern graphics cards bring impressive visuals and performance for gaming, 4K content, 3D rendering, creative applications, and select AI workloads.
