Buying a desktop PC: how to choose a model that suits the way you use it

Buying a desktop PC seems straightforward until you start comparing specifications. A low price may look appealing, but limited storage, little memory or an unsuitable graphics card can quickly lead to extra costs. Terms such as “gaming”, “AI-ready” and “powerful processor” also mean little on their own without concrete figures.

This practical buying guide helps you compare a desktop PC based on performance, size, connectivity and upgradeability. That way, you can find the right PC for working from home, studying, gaming, multimedia or professional use.

Three common desktop PC pitfalls

1. Looking only at the processor

A fast processor does not automatically make a computer suitable for every task. A graphics card is also important for gaming. For photo editing, video editing and large spreadsheets, memory and storage matter too.

An Intel Core i5 or AMD Ryzen 5 can be perfectly suitable for everyday use, but always check:

  • how much RAM is installed;
  • whether the PC has a dedicated graphics card;
  • how much storage space is available;
  • whether the processor is suitable for sustained workloads.

2. Mistaking a mini PC for a complete computer

A mini PC saves space, but it is not always fully equipped. A barebone PC may still require memory, an SSD and an operating system, for example. The MSI Cubi NUC 1MG-237BEU is a barebone PC that supports up to 64 GB of DDR5 memory and features several M.2 connections. This offers flexibility, but does require additional configuration.

Before buying, check whether Windows, RAM, an SSD and a power adapter are included.

3. Overlooking connections and room for expansion

A PC may be fast enough, but become impractical if it does not have enough USB ports or display connections. For a workstation with two or three monitors, HDMI, DisplayPort or Thunderbolt 4 are relevant. With a gaming PC, the maximum graphics card length and the power supply capacity are also important.

Which specifications are important?

Processor and memory

For office work, browsing, video calls and studying, 8 GB RAM is a useful starting point, but 16 GB RAM gives you more room for multitasking. For professional use, virtual machines or creative software, 32 GB or more may be appropriate.

When looking at processors, consider the number of cores and threads, as well as the generation and power profile. A modern mobile processor in a compact PC may be suitable for everyday tasks, while a desktop processor with higher power limits is better suited to sustained heavy workloads.

Graphics card

The integrated graphics in a mini PC or office computer are designed for displaying images, streaming and light graphics applications. For modern games, a dedicated graphics card is usually the more sensible choice.

An RTX gaming PC with a GeForce RTX 5050 or RTX 5060 Ti, for example, has dedicated graphics hardware for higher resolutions, ray tracing and supported upscaling technologies. When assessing one, check:

  • the graphics card model;
  • the amount of video memory;
  • the desired resolution, such as 1080p or 1440p;
  • the PC’s power supply and cooling.

Claims about image quality or performance depend on the software, settings and monitor used. So, pay particular attention to the listed hardware.

Storage, size and upgradeability

An SSD generally provides fast start-up and loading times. For a PC used for working from home, 512 GB is often practical; for several large games or video files, 1 TB may be more convenient.

A compact PC or all-in-one saves space, but often offers fewer upgrade options. A tower provides more room for additional storage, memory and a larger graphics card. Also check the noise level, ventilation and placement. Ventilation openings must not be covered, especially during intensive use.

Frequently asked questions about desktop PCs

Is a desktop PC suitable for working from home?

Yes. Look for at least 8 to 16 GB RAM, an SSD, a webcam or a suitable webcam connection, and enough USB ports. An all-in-one PC is practical if you want to keep your desk tidy. A mini PC is more convenient if you already have a monitor and peripherals.

How long does a desktop PC last?

Its lifespan depends on the workload, ventilation, component quality and upgrade options. A PC with replaceable RAM and additional storage space may remain useful for longer than a system with fixed memory. Regularly remove dust from the ventilation openings and do not place the computer in an enclosed cabinet.

How much electricity does a desktop PC use?

Power consumption varies depending on the processor, graphics card and usage scenario. A mini PC with a low-power processor generally uses less electricity than a gaming PC with a dedicated graphics card. Check the stated wattage of the adapter or power supply, but bear in mind that this is the maximum or rated power and does not always reflect actual consumption.
