Build a crazy gaming PC yourself: why focus on the motherboard rather than the latest processor
At the risk of being labeled a heretic by gaming purists, it must be said clearly: buying the latest ultra-powerful processor or the most recent and expensive graphics card does not automatically guarantee an exceptional gaming PC. Unless you have an unlimited budget and your goal is simply to achieve the highest benchmark numbers, this strategy is far from being the most effective.
In reality, investing in a high-end motherboard with the latest available socket offers much more flexibility and longevity. This approach allows you to upgrade your processor and even other components in the future , without being forced to change everything as soon as a new generation hits the market.
For the average gamer, or even the most demanding gamer, the difference in performance in most games will be almost imperceptible between a recent processor and the immediately preceding model. Only extreme situations – synthetic benchmarks or ultra-demanding games to maximize the number of FPS – will reveal a noticeable difference. In other words, a PC well designed from the start can remain powerful for several years , while offering the possibility of targeted upgrades.
In short, it's not about saving on raw power, but about thinking strategy and durability , as PC builders do: choosing the solid base that will allow you to build the gaming PC of your dreams, without having to reinvest massively every two years.

Choosing your motherboard: the key element for an upgradeable gaming PC
Choosing a motherboard requires a lot more thought than choosing a processor or graphics card . Whether you choose an AM5 socket for AMD or an LGA 1700 for Intel , it's essential to aim for a motherboard with a high-end chipset , as this determines all the features and scalability of your configuration .
The chipset influences several crucial elements:
The number and speed of PCIe slots , essential for fast graphics cards and peripherals.
Compatibility with NVMe , now essential for ultra-fast loading times.
The type, number and frequency of DDR memory , determining factors for fluidity in games and heavy applications.
Support for the latest generation of graphics cards , to ensure that your machine remains efficient over time.
Added to this is the size and format of the motherboard (ATX, Micro-ATX, Mini-ITX). This choice mainly depends on your aesthetic preferences and the space required in your case : a Mini-ITX will allow for a compact and minimalist assembly, while an ATX will offer more slots and expansion possibilities.
Simply put, a good motherboard isn't just a support : it's the heart of your gaming PC. Investing wisely here ensures flexibility, performance, and longevity , and allows you to upgrade your machine without being limited by outdated hardware choices.
Choosing your processor: prioritize intelligence over raw power
Choosing a good processor is primarily a matter of common sense , not a race to find the most powerful model on the market. For most uses, including office work and classic gaming , the performance differences are often imperceptible . It is only in extreme situations such as FPS-intensive games or intensive video editing that every core and every MHz really counts.
The advantage of thinking strategy rather than raw performance : you can upgrade your processor later , when prices have dropped, without having to change your entire configuration.
When it comes to choosing between AMD and Intel , it's mostly a matter of personal preference and compatibility with your motherboard - there's no wrong choice. Each platform has its strengths, and when combined with a capable chipset, it will offer longevity, stability, and scalability .
In short, a well-chosen processor from the start ensures that you have a high-performance PC today and ready for tomorrow's developments , without wasting money on unnecessary overkill.
Memory Choice: Opt for DDR5 and Optimize Speed and Latency
For RAM memory , it is now recommended to favor DDR5 , the latest generation available. Compared to DDR4, DDR5 offers higher frequencies and greater bandwidth , which improves performance in recent games and heavy applications such as video editing or 3D rendering.
There are two main factors that really influence performance: frequency (MHz) and CAS latency .
Frequency (MHz) : The higher the frequency, the faster the RAM can transfer data. For example, a 5200 MHz DDR5 is more efficient than a 4800 MHz DDR5.
CAS Latency (CL) : This is the number of cycles required to access a piece of data. A lower latency (e.g., CL36) allows for faster memory access, which improves system responsiveness, especially in competitive games or computationally intensive tasks.
The number of sticks also remains decisive: two or four modules in dual or quad channel allow you to maximize bandwidth , offering better fluidity and stability. A single stick limits the potential of your PC, particularly for gaming or content creation.
Finally, always check compatibility with your motherboard and processor to take full advantage of DDR5 speeds and optimized latency. A well-chosen DDR5 RAM, with optimized frequency and CAS and in the right number , guarantees immediate performance, fluidity and long-term scalability .
The hard drive: opt for an NVMe for blazing performance
Not so long ago, the classic SSD was considered the Rolls-Royce of disks , offering speeds already far superior to traditional HDDs. But today, it has been quickly overtaken by NVMe , which offers much higher speeds and performance.
For a gaming PC or a creative machine, you shouldn't limit yourself to an entry-level NVMe . High-end models like the Samsung Internal SSD 9100 Pro or the WD BLACK SN8100 1TB PCIe 5.0×4 offer exceptional read/write times and take full advantage of the latest generations of motherboards and processors.
The gain is immediate:
Ultra-fast Windows and application startup
Significantly faster file transfers
Increased fluidity in games and data-intensive software
By choosing a high-performance NVMe , you transform your PC's overall experience, with reduced loading times and maximum responsiveness . In other words, it's a key investment to fully enjoy your configuration today and tomorrow.
A gaming PC's graphics card: no need to aim for the extreme
So, let's be clear: if you're not a hardcore gamer or a professional video editor , there's no need to invest in a powerful graphics card. A mid-range graphics card , like a GeForce RTX 4060 or 5060 , is more than enough for most uses. In some cases, no dedicated card is even necessary , as many recent processors include a powerful graphics chip capable of handling games and light applications.
To take a concrete example: a few years ago, the GeForce RTX 1080 was considered high-end , while today an RTX 5060 surpasses it in almost every way.
While high-end graphics cards remain the most expensive component of a PC , the smart approach is to invest in a mid-range model that's sufficient for your current needs and plan for future upgrades if necessary. This allows you to enjoy solid performance without breaking the bank and remain flexible in the face of new generations of demanding games and software.
The case: between style, cooling and practicality
The case is not only the container of your PC , it is also a key element for ventilation, evolution and comfort of use . Choosing the right case depends on several criteria: size (ATX, Micro-ATX, Mini-ITX), airflow , noise level and design .
A well-designed gaming PC tower allows you to optimize the cooling of all your components , especially if you opt for powerful graphics cards or processors. Fans and cable routing directly influence system temperatures and stability.
Size and format also remain a matter of taste and space requirements : a Mini-ITX case is compact and ideal for a sleek desktop, while an ATX or E-ATX case offers more slots, more expansion possibilities and better airflow , at the cost of a larger footprint.
Finally, don't neglect design and practicality : glass panels, cable management, and dust filters make assembly more pleasant and maintenance simpler. A good case protects your components, facilitates upgrades, and enhances your entire setup .
Power supply: the backbone of your gaming PC
The power supply isn't just an accessory: it's the backbone of your gaming PC . A quality power supply ensures stability, longevity, and safety for all your components.
The choice is made mainly based on the required power and energy certification . An 80 Plus certified power supply (Bronze, Silver, Gold, or even Platinum) guarantees optimal performance, less heat and reduced consumption. For a mid-range gaming PC, 550 to 650 W is generally sufficient, while a very high-end or overclocked machine may require 750 W or more.
Besides power, cable modularity plays a practical role: a modular facilitates assembly, reduces clutter and improves airflow inside the case.
Investing in a reliable and suitable power supply not only saves you from stability issues, but also protects your components from power surges and premature failure. Simply put, a good power supply is a less visible but essential for the durability and performance of your PC.
