How to choose a desktop PC

Choosing a desktop PC depends on four main criteria: processor power, memory capacity, storage space and available connectivity. Configurations vary significantly depending on use: light office work, intensive multitasking or content creation.

What to check

Processor power The number of processor cores determines the computer’s ability to handle multiple tasks simultaneously. Current market configurations range from four cores for entry-level models to twenty-four cores for the most powerful workstations, with a median of twenty cores. The higher the core count, the better the score. A four-core processor suffices for routine office work, while video editing or modelling requires more cores to avoid slowdowns. Market median: 14.5
Memory capacity Maximum memory indicates how far you can upgrade your machine. Current desktops accept from eight to one hundred and ninety-two gigabytes of RAM, with a median of sixty-four gigabytes. The score reflects this maximum capacity: the higher it is, the better the score. This upgradability matters particularly if you plan to use demanding software or keep your computer for several years. Limited maximum capacity will force you to replace your machine sooner. Market median: 64 GB
Storage space Total storage capacity determines how many files, programs and documents you can keep locally. Capacities range from two hundred and fifty-six to two thousand gigabytes, with a median of one thousand gigabytes. The higher this value, the better the score. Generous storage avoids constantly managing available space or multiplying external drives. Storage type also matters: SSDs offer much faster access times than mechanical drives. Market median: 512 GB
High-speed USB ports The number of high-speed USB ports determines how many fast peripherals you can connect simultaneously. Desktop PCs offer from one to five third-generation USB Type-A ports, with a median of two ports. The score increases with this number. These ports accelerate file transfers from external drives or recent USB sticks. A limited number forces you to regularly unplug peripherals or invest in a hub. Market median: 3
Installation and upgradability A desktop PC usually stays in the same place, simplifying installation but requiring planning for power, network and peripheral cables. Check that the case allows easy access to internal components if you plan to add memory or storage later. All-in-one models integrate the screen and simplify installation, but often limit upgradability. Traditional towers offer more upgrade possibilities over time.

What you get for each budget

Less than €400

Entry-level models suit routine office work with four-core processors, limited memory and basic storage.

€400 to €900

This mid-range offers balanced configurations with faster processors, upgradable memory and comfortable storage for multitasking.

More than €900

High-end configurations provide the most powerful processors, large memory capacity and extensive storage for demanding professional use.

Frequent mistakes

Choosing too limited a maximum RAM capacity prevents any future upgrade without replacing the machine.
Neglecting the number of high-speed USB ports forces you to multiply hubs or slows file transfers.
Opting for minimal storage forces constant management of available space or multiplication of external drives.
Underestimating processor power needs leads to slowdowns as soon as several applications run simultaneously.
