Buying a desktop PC: how to choose the right model for you

Buying a desktop PC seems straightforward until you start comparing specifications. Many models boast a fast processor, AI features or a powerful graphics card, but that doesn’t automatically mean the computer is right for your workspace, games or software.

Most disappointing purchases come down to three common pitfalls:

  • Focusing too much on one component: an RTX graphics card won’t help much if the memory, cooling or storage doesn’t suit the way you use your PC.
  • Unclear Windows version: some gaming PCs come with an evaluation version of Windows. Check that Windows 11 Home is fully activated.
  • Overlooking size and upgrade options: a mini PC takes up little space, but often gives you fewer options for replacing the memory, storage or graphics card later.

Below, we compare the key choices to help you decide.

Which desktop PC is right for you?

1. Processor: there’s more to it than the number of cores

A multi-core processor is useful for multitasking, video editing and demanding software. For a PC for working from home, a modern Core 5, Core Ultra 5 or Ryzen 5 processor with 16 GB RAM is often a practical starting point. If you stream, edit or work with large files at the same time, you may benefit from a Core Ultra 7 or Ryzen 7 with 32 GB of memory.

Also consider the generation and type of memory. DDR5 is a newer standard than DDR4, but total capacity and upgrade options are just as important. Some compact models have memory that’s built in and cannot be replaced. That could be limiting if you need more memory later.

2. Graphics card: match it to your resolution and software

Integrated graphics are suitable for office work, videos and light creative tasks. For modern games, 3D software and video editing, you’ll usually need a dedicated graphics card.

  • RTX 5060 Ti: aimed at Full HD gaming and some 1440p setups.
  • RTX 5070: a more powerful choice for higher settings, ray tracing and creative software.
  • RTX 5080 or RTX 5090: designed for demanding gaming, rendering and AI workflows, with power consumption, cooling and the power supply requiring extra attention.
  • Radeon RX 9060, RX 9070 and RX 9070 XT: options for anyone looking for a gaming PC with AMD graphics.

The model name alone doesn’t tell you everything. Check the amount of video memory, the ports and the recommended power supply too. An RTX 5090 PC, for example, needs a roomy case, effective cooling and a suitable power supply.

3. Storage, connections and case

An NVMe SSD will generally start Windows and programmes faster than a traditional hard drive. For everyday use, 512 GB is a useful starting point; gamers and content creators will often be better off with 1 TB or 2 TB.

Also check:

  • how many USB ports are available;
  • whether the HDMI and DisplayPort connections are compatible with your monitor;
  • whether Wi-Fi and Bluetooth are built in;
  • whether there’s room for extra SSDs or memory;
  • how much space the case will take up under or beside your desk.

An all-in-one PC combines the screen and computer in a single case. This saves space and reduces cable clutter, but it’s often harder to upgrade than a tower. A mini PC is even more compact and suits a small workspace, while a gaming desktop PC usually offers better cooling and upgrade options.

Frequently asked questions about desktop PCs

How long does a desktop PC last?

Its lifespan depends on how you use it, how well you maintain it and whether you can upgrade it. An office PC can remain useful for several years. With gaming PCs, the graphics card and storage can become outdated more quickly as software requirements change. Choose a model with enough RAM, spare storage capacity and a case that allows good airflow.

How much does it cost to run a desktop PC?

Power consumption is mainly determined by the processor, graphics card and how long you use the PC. A mini PC generally uses less power than a powerful gaming desktop PC, while an RTX 5090 PC can draw considerably more under heavy load. Check the power supply’s wattage and switch the computer off when you’re not using it.

Can I set up a desktop PC myself?

Usually, yes. Connect the monitor to the right port, plug in the keyboard and mouse, connect an Ethernet cable or set up Wi-Fi, then follow the Windows installation steps. With a gaming PC that has a dedicated graphics card, you’ll usually need to connect the monitor to the ports on the graphics card, not those on the motherboard.
