Guide to Building a Gaming Computer

A Gaming Computer, also known as a gaming PC, can play computationally and graphically demanding video games. They are very similar to conventional computers, except they are fitted with a performance-oriented video card and other specifications. This type of computer can be easily bought in the market but at a much higher price than conventional computers. Since most games are both cost- and performance-conscious, most opt to build their gaming computer rather than buy a built-in gaming computer.


Building your custom gaming computer means you buy all components separately and piece them together to make your gaming PC. With this method, you can achieve a fast and cost-effective gaming computer suited to your gaming needs. Besides saving a lot of money and having an efficient machine, building your gaming computer can also be fun.

How do you choose your components?

  • [Native Resolution]

Perhaps the biggest challenge when building a gaming computer is choosing the right components for your needs. So, without further ado, here is a simple guide to help you make your gaming computer.

1. Central Processing Unit (CPU)

The Central Processing Unit (CPU) is one of computer systems’ most important core components. The CPU is a portion of the system that carries out the instructions of a computer program. In simple terms, it could be described as the brains of the computer. The performance of your games and other applications will depend on this microprocessor.

Choosing the best Central Processing Unit (CPU) for your gaming computer can be hard. Picking the latest, fastest, or most expensive processor on the market won’t always produce the right CPU for your particular system. Some processors are designed to work with specific motherboards. Thus, the CPU type limits the motherboard type you can use.

You will need a powerful CPU for a gaming computer to perform superbly. Luckily, Intel and AMD (Advanced Micro Devices) supply these CPUs at an affordable price.

Intel has the Core i7 and Core i5 processor models. These models are currently the most popular for gaming purposes, mostly recommended for gaming computers.

AMD, on the other hand, has the Athlon and Phenom series. Try the most recommended Phenom X4 series if you want to go AMD.

2. Motherboard

The motherboard is the hub of the computer system. It is where all other components are connected to. If we consider the CPU the computer system’s brain, then the motherboard is the central nervous system. Thus, buying the best motherboard is a good investment.

After choosing your CPU, you must consider choosing your gaming computer’s motherboard. When selecting a motherboard, you should remember three things.

First, a motherboard will generally support one type of processor only. Different CPUs have different connectors that vary physically; make sure your CPU plug is suitable for your motherboard connector.

Second, motherboards have a certain speed limitation depending on the processor model. The maximum processor speed allowed by the motherboard will be quoted in the motherboard specifications. Before buying, check whether your selected motherboard can support your chosen CPU.

Third, motherboards are the ones that can dictate the type and amount of RAM you can have. You would want to have either DDR SDRAM or RDRAM as a gaming computer, which is at least 1G worth. So ensure that your motherboard can support this type and amount of memory.

Here are some examples of well-known motherboard manufacturers where you can browse for your perfect gaming motherboard: ASUS, ABIT, MSI, XFX, EVGA, Intel, and Gigabyte.

3. Hard Drive

The hard drive is the computer component that stores your files and programs. When buying a hard drive for your gaming computer, consider these three main features: Speed, Size, and the type of Interface.

[Speed] Basically, the faster the hard drive spins, the quicker you can access and transfer your data. Currently, the best hard drives in the market can speed around 7200rpm (rounds per minute). You don’t want anything less than this; else, it will cause delays between reading and writing data.

Faster hard drives that reach 10,000rpm and 15,000rpm are available at a higher price in the market. A 7200rpm hard drive is already enough for your gaming computer, but if you can shell out more money, you can opt for these faster hard drives.

[Size] Hard drives come in different sizes, ranging from 80GB to 500GB. It is always recommended that your gaming computer purchase the largest hard drive you can afford. This will allow you to store lots and lots of software and data (including games).

[Interface] The hard drive interface manages data exchange between a computer and the hard drive. Currently, the most commonly used hard drive interface is Advanced Technology Attachment (ATA), which comes in two forms: the original Parallel ATA (PATA) and the newer and faster Serial ATA (SATA).

The expensive Small Computer System Interface (SCSI) is also used primarily for high-end workstation computers. It is sufficient for your gaming computer to have SATA if your motherboard can support it.

4. Video Card

Choosing the right video card supported by your CPU and motherboard is critical and tough. The gaming video card you choose will produce the dazzling 3D graphics and effects seen in the latest computer games. A better graphics card can deliver a better 3D gaming experience, so the best and most affordable video card should be bought for your gaming computer.

The graphic processing unit (GPU) can be connected to your motherboard through an AGP or PCI Express slot. It is recommended that your gaming computer use a graphics card associated with a PCI Express slot on your motherboard.

The GPU’s Speed and efficiency should not be the only thing that counts when buying your video card. It would also help if you considered the advanced 3D rendering effects, such as anti-aliasing, anisotropic filtering, bump-mapping, pixel shaders, and much more. Consider a video card that can support the latest 3D rendering techniques in the software world for your gaming computer.

Like the CPU market, two competing companies dominate the graphics card. These companies are ATI and Nvidia. ATI is responsible for the Radeon series, while Nvidia is marketing the GeForce line of cards.

5. Power Supply

The power supply is a vital and overlooked component of the computer system. Without a power supply, the computer cannot operate its functions. Its main purpose is to convert AC power from the mainline to usable low-voltage DC power for the computer’s internal components. The power supply gives your laptop three different DC voltages: 12VDC, 5VDC, and 3VDC, which are used differently by computer components.

Each power supply has a certain amount of energy or wattage based on its maximum output power. Wattages range from 300W to 500W, but some high-end gaming power supplies can reach 800W to 1kW.

If you want to use a power supply for your gaming computer, it is recommended to have at least a power supply ranging from 500W and above.

6. Gaming Monitor

One of your gaming computer’s most expensive components is the computer monitor. When buying a gaming computer monitor, you only need to consider Size, native resolution, and price.

[Size] Computer monitors come in different sizes,, from the small 15 inches to a larger 23 inches, and even larger. Seventeen inches is a common size and large enough for most people, but a larger monitor is advisable to increase your viewing and gaming experience.

[Native Resolution] Each monitor has been designed for a certain resolution known as the native resolution. SupposeSuppose you change the resolution of a monitor to a solution that doesn’t coincide with its native resolution. In that case. In that case, the image will be scaled, and the quality will be lessened significantly. The native resolution of a monitor is dependent on its Size. Here are some examples of native resolution for common sizes:

  • 17 inches 1024×768
  • 19 inches 1280×1024
  • 20 inches 1600×1200

[Cost] Prices vary greatly between sizes, where smaller ones cost cheaper than larger ones. So,, choose a size that can satisfy your needs while considering your budget.

7. Gaming Keyboard

Custom-built Keyboards designed specifically for gaming can give an edge to a gamer using them. But currently, no general gaming keyboard can be recommended for all gamers. Why? This is because different gamers have different or varying play styles, posture, and wrist anatomy. So basically, there is no such thing as a gaming keyboard that is best for everyone.

According to Build-Gaming-Computers, one of the best gaming keyboards available in the market is the Logitech G15 Gaming Keyboard. This keyboard has been custom-made to meet a gamer’s needs. It specifically features:

a. An adjustable, backlit LCD screen that displays important in-game information during gameplay;

b. Backlit keys to play in the dark or low-lit areas;

c. 18 programmable “G-keys” used to execute macros; and

d. Timer controls to keep track of game events.

8. Gaming Mouse

Choosing the best gaming mouse can help increase your gaming experience level, like the gaming keyboard. Using a custom-designed gaming mouse gives the best accuracy and control, which allows you to play games at your best.

Computer mouse comes in different types: the optical, laser, and ball mice types. Optical and laser-type mice are commonly used due to their precision and better tracking, allowing for more accuracy and control.

It would help if you considered several factors when selecting the best mouse for your gaming computer. One of the most important ones is the resolution. Resolution is the number of pixels per inch a mouse’s optical sensor and focusing lens can see when you move the mouse around. The higher the resolution a mouse has, the better the accuracy and precision.

Next, consider the responsiveness of the mouse. It is the number of megapixels per second the mouse can process. This is important, especially in fast-paced games such as first-person shooter games. The more megapixels per second the mouse can process, the more responsive it is; thus, it offers faster and more precise control in your games.

So when buying a, gaming mouse, consider the resolution and responsiveness of the mouse you are going to bwillaming Computer Builds
