Buying Guide: Which Gaming PC Should You Choose? (2026)

Short answer: A gaming computer is chosen based on four things, in this order: what you play, what resolution and frame rate you want (1080p, 1440p or 4K), your budget and how long you want the computer to last. The graphics card (GPU) is the single most important part for gaming performance, followed by the processor (CPU), and then memory (RAM) and fast storage (SSD). A good rule of thumb: put the largest part of your budget on the graphics card, have at least 16 GB of RAM and an SSD, and choose a computer that is upgradeable.

At TNS Gaming you always get 1 year warranty and free shipping, and you can configure the computer with optional RAM and SSD before you buy. You can also pay with Klarna (split or pay later) or Swish.

Desktop gaming computer or gaming laptop?

Short answer: Choose a desktop gaming computer if you want the most performance for your money, quieter cooling and the ability to upgrade. Choose a gaming laptop if you need to be able to bring your computer or are short on space.

For most home gamers, a desktop computer is the better choice. A laptop is right if portability is more important than maximum performance.

What parts are most important in a gaming computer?

Graphics card (GPU) – most important for gaming. Decide what resolution and frame rate you can handle. If you have a limited budget, prioritize the graphics card.

Processor (CPU) – second most important. Feeds the graphics card with data. A CPU that is too weak can bottleneck a strong graphics card, especially in 1080p and in games with a lot going on at the same time.

Working memory (RAM) – 16 GB is the minimum for modern gaming today. 32 GB gives you margin if you stream, have many tabs open or play the most demanding titles.

Storage (SSD) – always choose an SSD, not a hard drive, as your system drive. Games load faster and your computer feels faster overall. 1 TB is a good starting point; large game libraries will want more.

With us, you can increase RAM and SSD as an option directly when you configure your computer, so you don't have to upgrade yourself afterwards.

How much RAM and storage do I need?

• 16GB RAM / 1TB SSD – good base for most players.
• 32GB RAM / 2TB SSD – for those who play demanding titles, stream/record, or even work and edit on the computer.

A common mistake is to skimp on RAM and storage but spend too much on other things. The right balance makes your computer feel fast in everyday life, not just in games.

Which gaming computer is suitable for 1080p, 1440p or 4K?

The resolution you play in determines how powerful your computer needs to be:

• 1080p (Full HD) – most common and most affordable. An entry-level to mid-range computer will go a long way and provide high frame rates in most games. Best performance per dollar.
• 1440p (QHD) – the popular middle ground in 2026: sharper image than 1080p without the high demands of 4K. Requires a mid- to high-end graphics card.
• 4K (Ultra HD) – sharpest, but most demanding. Requires a top-of-the-line graphics card for high frame rates.

Tip: Match your computer to your monitor. A powerful computer connected to a simple 1080p monitor won't be fully utilized – and vice versa. See our full range of gaming computers.

New or used gaming computer?

Both and can be right – it depends on budget and needs.

• New computer provides the latest hardware, full lifespan and maximum future-proofing.
• Used computer provides more performance for the money and is a smart, more sustainable choice if budget is in focus.
