How to Build the Ultimate Gaming PC 2021

If you want to compete at the highest level your need the best tools available. With so many moving parts inside a PC, it’s crucial to limit the impact it has on performance.

Choosing the best available hardware components is essential for a gaming computer. It’s more than picking the most expensive, and the highest specced parts, however.

Different pieces of hardware, from different manufacturers, are created differently. Gaming performance is more than FPS, Input-lag and Frame-timing are arguably more important.

Follow this guide to find the best synergies and the best parts for the overall best gaming PC. We will break it down to each component, as well as how to bring it all together to complete the package.

What is the ultimate gaming PC?

What’s the best Gaming CPU?

This is probably the most controversial topic right now since AMD made such a huge impact during 2020.

The AMD Ryzen CPUs are undoubtedly more advanced and have the best multi-threaded performance, along with power efficiency.

In order to create their CPUs with a large core count, they have bridged chips together using various methods which will add latency.

Feeding high refresh-rate monitors with more than 240 fps require a really high frequency that Intel can provide.

Games are still mostly relying on the frequency and rarely utilize more than 4-6 CPU cores.

  • Disable Hyper-Threading for 6-core CPUs as it may add latency.

Hyper-Threading is also a security hazard and is constantly patched which will reduce performance over time.

Intel is the most established manufacturer and has the best support from Microsoft and Windows.

What’s the best RAM?

Not all chips are created equally and some specific models and samples will perform better.

  • Samsung B-die is generally considered the best option for the best performance.

Amount of RAM

The amount of RAM required for gaming is far from what’s required in media creation.

In order to make larger chips, the speed and performance will take a hit because of technological limitations.



The speed of the RAM is far more important and it’s always recommended to enable XMP to ensure peak performance during gameplay.

What’s the best SSD?

What’s the best GPU?

Graphics drivers support really important since it usually directly impact game performance.

AMD has been having stability and performance issues with its GPU drivers in recent years.

Nvidia has (thanks to marketing) been able to achieve the best adoption of specific performance-enhancing features such as Reflex and another input-lag tech.

However, AMD had a strong 2020 and there are reports of AMD having better “raw” performance in (older) competitive games.

What’s the best Motherboard?

Use a model with Intel NIC for the best network performance.

Option to set HPET is desirable.

Ability to set XMP

What’s the best Cooling?

Use an air-cooler for reliability.

Enough cooling is important to allow your hardware to run at full speed with performance hits.

AIO water cooling can look awesome but there is always a risk of failure thanks to the added moving parts inside.

Often referred to as DC power.

Stuttering may occur when the temperature rises and the fans are not updating fast enough. This can cause throttling and crippled performance in a worst-case scenario.

The Best CPU For Gaming

In 2021 Intel is still the recommended brand for High Refreshrate gaming.

We recommend at least 6 cores for modern games and remember to disable Hyper-Threading.

K-series SKUs come with the highest clock frequency for high FPS gaming.

For 240Hz (FPS) and above close to or above 5 GHz is recommended.

Core i9 has the best available hardware from the factory and are handpicked for their performance.

i9 also has the highest frequency out of all CPUs.

i7 are usually damaged chips with disabled cores which may add latency thanks to re-routing inside the unit.

The Best Gaming PC Motherboard

Intel networking on the motherboard is preferred thanks to its proven track record for performance.

Asus is our recommended brand because of its long tradition of stability and support.

Driver and firmware support is crucial to avoid problems down the line.

(Avoid RGB and brand-specific software suits with unnecessary features).

Sound is important if you want to use the onboard audio for your headphones.

The Best RAM

XMP-enabled DDR4.

Always use dual-channel memory by making sure you buy a kit of 2x RAM modules.

Samsung is generally the best manufacturer of RAM chips and can provide performance.

Find the RAM with the lowest CAS latency specification while using XMP.

16 GB RAM is currently our recommendation for pure gaming.

B-dye selection of memory is the best option.

Graphics Card (GPU)

We recommend Nvidia GPUs for the best performance and most advanced features for competitive gaming.

Newer games rely more on the GPU to produce higher resolution textures while older games played at high FPS are still more reliant on the CPU.

Pick a GPU with Reflex support to assist with reduced Input-lag in newer titles such as Valorant.


Set fans to constant speed to avoid heat spikes and lag because of throttling.

Use an air-cooler for reliability.

We currently recommend Noctua as our premium pick while Cooler Master is the more affordable option.

Avoid RGB-functionality on fans which is generally a bad option and will most likely introduce more cable clutter inside the case.
