Buying a gaming PC: how to choose a desktop that suits your games

Buying a gaming PC seems straightforward until you start comparing specifications. A powerful graphics card might be paired with little memory, a small SSD or a power supply that leaves little room for upgrades. Terms such as “AI”, “future-proof” and “extreme performance” also tell you little about how a PC will perform for your everyday needs.

As a Joybuy Product Recommendation Officer, I focus on specifications you can verify. This helps you avoid paying for lighting or marketing claims when the components don’t suit your games, monitor or creative work.

Common pitfalls when buying a gaming PC

1. Focusing only on the graphics card

The graphics card has a big impact on graphical performance, but the processor still matters for esports, simulations, streaming and high refresh rates. An RTX 5060 gaming PC with a suitable Ryzen 5 or Intel Core processor can be a sensible choice for Full HD. For more demanding 1440p or 4K settings, you’ll also want more graphics memory and a more powerful GPU.

Be sure to check the difference between a desktop card and a laptop card, too. An RTX 5060 Laptop GPU isn’t automatically equivalent to a desktop RTX 5060. Manufacturers can adjust the power consumption and clock speed.

2. 16 GB RAM without a plan to upgrade

A gaming PC with 16GB RAM is suitable for many games and everyday use. However, streaming, video editing, CAD and running several programmes at once can make 32 GB a better option. Check the number of memory slots and the maximum capacity before you buy.

For example, the Lenovo Legion T5 comes with 16 GB DDR5 and can be upgraded to 32 GB. That’s more specific than simply saying a system is “ready for the future”.

3. Not checking Windows, accessories and storage

Not every computer comes with the same Windows licence. Some models have Windows 11 Home, while others are listed with an evaluation version. Check whether a keyboard, mouse, Wi-Fi adapter and power cable are included, too. Some product listings state that a charger isn’t included as standard, so check the current box contents before buying.

A gaming PC with a 1TB SSD generally gives you more practical storage than a model with 480 or 500 GB. Modern games can take up a lot of space. An NVMe SSD with PCIe 4.0 is also a clear, verifiable specification for fast system and loading times.

Key specifications explained

Graphics card and resolution

Choose a graphics card to suit your monitor:

  • 1080p: An RTX 5060 gaming PC is a sensible category for Full HD games and esports.
  • 1440p: An RTX 5060 Ti gaming PC or RTX 5070 gaming PC gives you more room to increase settings, depending on the game.
  • 4K: Look for an RTX 5080 gaming PC, plenty of VRAM and support for features such as ray tracing and DLSS. NVIDIA and manufacturer information confirms that these features only work in supported games and settings; they don’t automatically guarantee the same frame rate in every game.

The RTX 5060 Ti systems mentioned here have 8 GB of graphics memory. The RTX 5070 configurations in this selection have 12 GB, while the RTX 5080 desktop has 16 GB. These are useful points of comparison, but overall performance also depends on the processor, cooling, game settings and resolution.

Processor: Ryzen gaming PC or Intel gaming PC?

A Ryzen gaming PC could be a good choice if you game, stream and use several applications. The manufacturer links the Ryzen 7 7800X3D in some systems to 3D V-Cache. This is a processor feature, not a guarantee of a fixed frame rate in every game.

An Intel gaming PC may suit you better if you’re looking for a combination of gaming, rendering and general productivity. As well as the name, check the number of cores and threads, maximum turbo frequency and motherboard platform. An Intel Core i5-14400F, for example, is in a different class from an Intel Core i7-14700F or Core Ultra 7 265F.

Cooling, power supply and upgrades

A desktop gaming PC needs to be able to dissipate heat. Check:

  • the type of cooling: air cooling, 240mm or 360mm liquid cooling;
  • the number of fans and the case’s airflow;
  • the power supply’s wattage and efficiency rating;
  • available RAM, M.2 and expansion slots;
  • the case dimensions and clearance around the PC.

An 850W power supply in a more powerful system can leave more headroom for higher-power components. A compact MSI case with a 500W power supply may be a good fit for an RTX 5060 Ti configuration, but leaves less room for demanding upgrades. Always check the full configuration table.

Frequently asked questions about gaming PCs

Is 16 GB RAM enough for a gaming PC?

16 GB of memory is suitable for many games. For streaming, video editing, CAD and intensive multitasking, 32 GB gives you more headroom. Always check whether the system can be upgraded and whether any memory slots are free.

How long does a gaming PC last?

Lifespan depends on the games you play, resolution, settings, ventilation and maintenance. Keeping the ventilation free of dust, installing up-to-date drivers and having enough storage can help keep the system practical to use. When buying, check the warranty period and whether you can upgrade the RAM, SSD or graphics card.

How much does it cost to run a gaming PC?

Energy use depends on the power supply, the actual power consumption of the processor and graphics card, and how many hours you play. An 850W power supply doesn’t use 850 watts all the time; that’s its maximum power output. For a more accurate picture, measure consumption with an energy meter plugged in between the mains socket and the PC.
