Ensuring that your hardware is properly balanced can prevent a PC performance bottleneck and result in an all-around better user experience.
Building a quality gaming PC isn’t as simple as buying the most expensive CPU or GPU. A holistic and balanced hardware setup is critical for an ideal user experience.
A “balanced” PC is one in which the hardware is equipped for the workloads the machine will be handling, such as gaming, and should be designed to avoid “bottlenecks.” With a properly balanced PC, your components will achieve the level of performance they were designed for, without any one component (or set of components) being disproportionately over or under-utilized. This means a better gaming experience and a better user experience overall.
All PCs should be properly balanced, but we’re mostly going to focus on the hardware of a system designed for gaming. Many of the recommendations will apply to other systems as well.
What is a PC Bottleneck?
In the context of a PC, a bottleneck refers to a component that limits the potential of other hardware due to differences in the maximum capabilities of the two components.
A bottleneck isn’t necessarily caused by the quality or age of components, but rather their performance. Bottlenecks aren’t unique to high-end systems either; balance is equally important in systems with more entry-level hardware.
Finding a Compatible CPU and GPU
Bottlenecks are not exclusive to the CPU and GPU, but the interplay between these two components illustrates how a bottleneck can impact a system.
The central processing unit (CPU) is responsible for calculating operations like physics, audio, netcode, positional data, and countless other systems in modern PC games. It also sends rendering instructions to the graphics processing unit (GPU).
These instructions from the CPU contain everything the GPU needs in order to know what to render, including shaders, textures, and other visual data. They are then executed by the GPU, resulting in the image you see onscreen. If the GPU is rendering these instructions faster than the CPU can provide them, the GPU will remain idle until the next set of instructions is ready.
This means the GPU is not operating at peak performance, and this can result in fewer frames per second being rendered. This is a bottleneck in that the performance level of the GPU is being restrained by the limitations of the CPU.
The same can happen in the opposite direction. If a powerful CPU is sending instructions to the GPU faster than the GPU can render, the capabilities of the CPU are being limited by the slower speeds of the GPU. The system would perform better with a CPU and GPU that are more closely matched in performance capability.
Again, almost any hardware can contribute to a bottleneck, not only the CPU and GPU. Ideally, system hardware will work as close to maximum performance as possible, and one link in the hardware chain will not detrimentally impact the others.
Building a Balanced Gaming PC
When planning a new build, consider not only the type of games you play and their hardware requirements, but also how each piece of hardware can potentially impact the others.
CPU
Though games are optimized differently, and some are more CPU-dependent than others, a high-performance processor is still critical to an ideal gaming experience and is a great place to start when planning a new build. The hardware needs of someone playing a CPU intensive title while live streaming will be different from someone who occasionally plays less hardware intensive games. Think about which more closely aligns with how you use your PC.
After choosing the right CPU for your system, next consider the GPU you are planning to pair it with in order to achieve a balanced build.
GPU
As with the CPU, choosing the right GPU will depend on the games you play and how you plan to use the system.
Most PC games provide extensive graphics options that allow you to customize your experience. This often means you can experience newer games with an older or more entry-level GPU, though there may be some performance concessions, as well as an impact on the overall look and feel of the experience.
If higher resolutions are a priority, a high-end GPU is probably going to be the best fit. If 1080p gaming is sufficient, your options open up considerably.
In order to ensure a balanced build, your CPU and GPU should be more than just compatible — they should be complementary. The latest Intel® Core™ i5 processor is an excellent entry-level CPU, but your system will not be properly balanced if it’s paired with a GeForce* RTX 3090 GPU. Likewise, the latest Intel® Core™ i9 gaming processor is a great choice for a powerful gaming CPU, but when paired with an entry-level GPU, the CPU’s full potential will be unnecessarily limited.
The CPU and GPU work together closely in a gaming PC, and as such, it’s best not to prioritize one to the detriment of the other. Both should enable the other to operate at the highest possible level of performance.
RAM
RAM isn’t usually a bottleneck when gaming, unless you don’t have enough. For most modern games, 8GB of RAM is a good baseline, though 16GB is quickly becoming the standard. It also depends on how you use your computer; if you’re only playing a game, you’ll need less RAM than if you’re also chatting on Discord or streaming video while playing.
Generally speaking, when it comes to gaming, speed is less important than quantity. Again, the idea is balance, so 16GB of very slow RAM is not ideal. But as long as you’re purchasing modern memory, 16GB of DDR4 RAM is usually preferable to 8GB of DDR4 with a slightly higher speed.
SSD/HDD
Display
Your display can also act as a bottleneck. You won’t be getting the most out of the latest gaming hardware if you’re using a 60Hz, 1080p display.
If you’re aiming for higher frame rates or resolutions, you’ll want to make sure you invest in a display that can properly showcase these features, along with a balanced CPU and GPU combination capable of rendering them.
Other Hardware
Though CPU, GPU, RAM, storage, and display have the most substantial impact on gaming performance, other components also need to be considered for a balanced build.
The power supply might not directly impact frame rates, but a mismatched PSU can still pose a risk to the longevity of your system.
A motherboard probably won’t affect gameplay, but it can limit your hardware options, make future upgrades more difficult, and impact some quality of life features like network connectivity and sound.
Every piece of hardware should be considered in the context of how it will work with everything else in the system and help to cultivate a more balanced experience.
How to Balance Your Build
One of the advantages of pre-built PCs is that they are usually designed to be balanced. If you are building or upgrading your own system, however, you want to buy hardware that isn’t just compatible but complementary from a performance perspective.
Consider the best way to disperse your budget. You want the highest quality components, but you also want to prioritize for your needs. For example: If you want a higher resolution experience, allocating your budget to accommodate a higher resolution display and high-end graphics card is ideal. If you play fast-paced shooters like Call of Duty: Warzone or VALORANT, prioritizing a high frame rate with the right gaming CPU and a higher refresh rate display makes sense.
Examples of Balanced Builds
What follows are a few examples of balanced systems, which might be a useful point of reference when considering a pre-built or custom PC.

hat you’re looking for from a gaming PC may vary, but whatever hardware you select, ensuring that it’s properly balanced will result in a better experience. When putting together your PC, keep in mind that you can always upgrade later. It’s preferable to have a balanced build you can upgrade rather than one very powerful component in a system that otherwise lags behind.
A balanced build goes beyond ensuring a better gaming experience. It’s about putting together a system that will perform at its best regardless of how you use it. Whether you’re gaming or creating, prioritizing balanced hardware will result in a better all-around experience.
