Pay for your PC in installments (up to 12 payments)Overclocking your gaming PC: a good idea or an unnecessary risk?
Overclocking a gaming PC is a technique that involves increasing the frequency of a processor or a graphics card to gain more FPS in games.
In 2026, as components are more powerful than ever, the question comes up again and again: do you really need to overclock your CPU or GPU to get more FPS? Is it still useful with modern technologies (DLSS 4, Frame Generation, etc.)? We explain everything.
What is overclocking (and what is it for)?
Overclocking means increasing the clock frequency of a component (processor or graphics card) beyond its factory specifications. The goal: improve performance in games or productivity.
But beware: higher frequency also means higher power consumption and higher temperatures. Hence the importance of having a good power supply, suitable cooling, and a properly configured BIOS/UEFI.
CPU overclocking: useful for gaming?
In 2026, most modern gaming CPUs (such as the AMD Ryzen 7 7800X3D or Intel Core i5 14600KF) are already optimised for high turbo boost frequencies. For certain tasks (compilation, 3D, and very CPU-limited games), manual overclocking can still squeeze out a few more FPS… but the gain is often marginal.
➡️ In short: for CPUs like the Ryzen 7 9850X3D or the Intel Core i7 14700KF, the performance/power consumption/risk ratio of overclocking isn’t always compelling for pure gaming. That said, it can be useful for gaming PCs built around Ryzen 5 7500F or Intel Core i5 12400F, with good cooling.
GPU overclocking = more FPS?
On graphics cards, the margin is often a little wider. For example, some RTX 5070s or RX 9070 XT cards can gain 5 to 10% performance with well-calibrated overclocking (via MSI Afterburner or the manufacturer’s software).
➡️ The real gains are mainly seen in AAA games at 1440p or 4K, where the GPU is the limiting factor. However, watch out for visual artefacts or crashes if the overclock is too aggressive.
Is overclocking risky in 2026?
Less than before, but…
With modern motherboards (MSI B760, B850, X870), thermal protections are much better. FlowUP PCs are shipped with up-to-date BIOS, tested XMP/EXPO profiles, and suitable cooling (240 or 360 mm watercooling on higher-end models).
Discover our gaming PCs that you can potentially overclock
But overclocking is still a manual setting:
- It can invalidate certain warranties (depending on the manufacturers).
- It requires stability testing (OCCT, Cinebench, 3DMark).
- It increases power consumption, so you need a solid PSU (at least 650–850W for recent GPUs).
How to overclock your gaming PC?
To overclock a gaming PC, you generally need to go through:
- the BIOS/UEFI for CPU overclocking
- software such as MSI Afterburner for GPU overclocking
It’s essential to test stability with tools like OCCT, Cinebench or 3DMark to avoid crashes and artefacts.

Verdict: should you overclock your gaming PC in 2026?
Want to learn, test, push 5 to 10% higher? Overclocking is still an option… especially on graphics cards. But it’s no longer a necessity like it was back in the Core 2 Duo days. Modern CPUs are already very fast out of the box, particularly AMD’s X3D chips or Intel’s K models.
The FlowUP PCs are designed to deliver optimal performance without overclocking, but they still leave you free to fine-tune things if you want to go further. And above all, they’re tested and validated to run stably, which makes overclocking safer.
FAQ PC overclocking for gamers
is it dangerous to overclock your gaming PC?
No, not if it’s done properly. A poorly set overclock can cause overheating, crashes or instability, but with good cooling and stability testing, the risk remains limited.
What FPS gain with a GPU overclock?
A GPU overclock often brings an extra 5 to 10% FPS. The improvement is most noticeable in 1440p and 4K on demanding games.
Do you need water cooling to overclock?
Not necessarily. A good air cooler or good airflow can be enough. Water cooling is mainly useful for a more aggressive CPU overclock.
Is it worth overclocking your CPU in 2026?
Not always. Recent CPUs such as the Ryzen X3D or the Intel Core K models are already very powerful out of the box. For gaming, the gain is often small.
How can you tell if an overclock is stable?
You need to use software such as OCCT, Cinebench or 3DMark. If the PC crashes, gets too hot or shows artefacts, then the overclock isn’t stable.
CPU overclocking or GPU overclocking: which is more worth it?
In general, GPU overclocking is the most cost-effective way to get more FPS in games. CPU overclocking is often less useful on a modern gaming PC.
