Buying a gaming PC: how to choose a system that suits your games and budget

Buying a gaming PC seems straightforward until you start comparing the specifications. A striking RGB case, a powerful graphics card and plenty of storage don’t automatically mean the system is right for you. Compatibility, cooling and upgrade options are what determine whether your purchase will remain practical in the long term.

Common pitfalls when choosing a gaming desktop PC

1. Looking only at the graphics card

An RTX 5060, RTX 5070 or Radeon RX 9070 XT immediately catches your eye, but the rest of the configuration matters too. A processor that isn’t a good match, limited RAM or an underpowered PSU can affect the overall experience. Always consider the processor, graphics card, RAM, storage and cooling as a whole.

2. Mistaking RGB for performance

An RGB gaming PC can look great, but lighting won’t improve your frame rate. Instead, check how many fans are installed, which radiators will fit and whether the PC case has enough room for your graphics card and CPU cooler.

3. Underestimating how much storage you need

An NVMe SSD gets Windows and games up and running quickly, but 480 GB or 512 GB can fill up fast if you store several large games, video files and programmes. A 1TB NVMe SSD gives you more practical storage space. Also check whether the motherboard has an extra M.2 slot for a future upgrade.

The key specifications explained

Graphics card and resolution

For many gamers, the graphics card is the most important component. According to the product description, a system with an RTX 5060 is designed for gaming at 1080p and 1440p. The ASUS ROG systems with an RTX 5070 pair that GPU with 12 GB of GDDR7 memory. This may appeal if you want higher settings, play demanding games or use applications such as rendering software.

Don’t just look at the model. Check the following too:

  • The amount of video memory in GB.
  • The length and thickness of the graphics card.
  • The connections for your monitor.
  • The recommended PSU.
  • Support for features such as ray tracing or DLSS, if they’re relevant to the games you play.

According to ASUS’s product description, the Prime Radeon RX 9070 XT OC Edition supports 16 GB GDDR6, PCIe 5.0, HDMI 2.1b and DisplayPort 2.1a. These are verifiable product specifications; actual performance depends on the game, settings and other hardware.

Processor, motherboard and RAM

Both an AMD Ryzen gaming PC and an Intel gaming PC can be suitable. Pay particular attention to the number of cores, generation, socket type and upgrade options.

For a self-built system, the processor and gaming motherboard must use the same platform. The COLORFUL BATTLE-AX B650M models use the AMD AM5 socket and, according to the product information, support Ryzen 7000, 8000 and 9000 processors. They work with DDR5 RAM, but not DDR4 or DDR3.

The practical difference between the two motherboards mentioned is:

  • The B650M Frost WIFI V15 has four DDR5 slots, supports up to 192 GB and has two M.2 slots with PCIe 5.0/4.0 x4 support, depending on the CPU used.
  • The B650M-E WIFI V14 has two DDR5 slots, supports up to 96 GB and has two M.2 slots with PCIe 4.0 x4.

Check the manufacturer’s memory compatibility list before you buy. A DDR5 kit such as 32 GB DDR5-6000 will only run at the stated speed if the motherboard, processor and memory profile support it. XMP and EXPO are settings you can enable in the UEFI/BIOS if needed.

Case, cooling and PSU

Measure the available space before ordering a PC case or complete gaming PC. The MSI MAG PANO M100R PZ supports micro-ATX and mini-ITX and accommodates graphics cards up to 350 mm long. The Corsair 3500X ARGB supports cards up to 410 mm and larger motherboard formats.

Also check:

  • Maximum CPU cooler height.
  • PSU length.
  • Available fan mounts.
  • Support for 240 or 360mm liquid cooling.
  • Dust filters and cable management space.

A larger case isn’t always necessary, but it can make installation and future upgrades easier. Keep the vents clear and place the PC somewhere stable and dry.

Frequently asked questions about gaming PCs

How much RAM does a gaming PC need?

For most new games, 16 GB of RAM is a practical starting point. If you stream, edit video or keep lots of programmes open at the same time, consider 32 GB of DDR5 or DDR4. Always check which type of memory your motherboard supports.

Is Wi-Fi useful on a gaming PC?

Yes, especially if it’s difficult to run an Ethernet cable to your desk. A built-in Wi-Fi 6 card, as found on certain B650M motherboards, is generally neater than a separate adapter. For a pre-built system, check whether Wi-Fi is built in or supplied via USB.

How much does a gaming PC cost to run?

Power consumption depends on the graphics card, processor, monitor, settings and how many hours you play. A more powerful system with an RTX 5070 will generally use more electricity than a configuration with an RTX 5060. Check the PSU’s rated output and use sleep mode when the PC isn’t in use.
