Things You Should Know Before Buying a Gaming PC

With the unlimited innovative games released every day, the desire for having a modern gaming PC build never goes out of fashion. If you’re someone new to the world of custom PC and want to make one, your venture is not an easy one. High-end games require PC builders to be meticulous in choosing hardware. They should have in-depth knowledge of the latest releases, their compatibility, and coordinating scopes. 

One wrong choice may create a fissure that will only drain your setup’s ability to perform at its highest optimal level. Regardless of your current level of knowledge in the custom-built PC field, this guide is designed to complement and transform you into a rockstar PC builder.

Determine Your Gaming Goals

Every setup needs a plan to be executed well. You should be thoughtful while figuring out what you mean when you think of a great PC build. And while doing so, don’t let any stereotypical thought infest your desire. However, price should always be a consideration.

Casual gamers who like to play indie games, Sims, or older AAA titles can manage with budget builds using integrated graphics or entry-level GPUs like the GIGABYTE Intel Arc A310 WINDFORCE or GIGABYTE Intel Arc A380.

Mid-tier gamers who live and die over GTA V, FIFA 24, and COD: MW2 should choose a slightly more robust setup. They should go for processors with higher clock cycles and threads.

Top-tier gamers who want to sit on the tallest branch of the tree so that they can get the holistic view should go for a holistic setup. A holistic setup is made of the most powerful and latest components. But it doesn’t mean that they should randomly buy every brand’s latest launches. Their focus should be on choosing components that help each other perform at their peak.

Understanding Key Gaming PC Components

This is the part you should be most careful about. Because overlooking any detail here will impact your build’s performance, ultimately your experience. The indispensable parts of a gaming system include:

Processor

The central processing unit (CPU) is the brain of your gaming PC. Ideally, go for the latest generation processor, like AMD Ryzen 7000 series or Intel’s 13th or 14th Gen Core series.  Ensure compatibility with modern game engines and upcoming titles. 

For casual or indie games, older processors like Ryzen 5 5600X or Intel i5-11400F can still offer good performance. However, for AAA titles, open-world games, or heavy multitasking, opt for at least an Intel i7 or AMD Ryzen 7 with the maximum core and thread count.

Video graphics card

The graphics processing unit (GPU) determines how smoothly your games run and how good they look. For 1080p gaming at 60 frames per second, a midrange GPU is sufficient. For 1440p or 4K at high frame rates, you’ll need high-end options. 

Also consider VRAM size, 8GB is the minimum for most modern games, while 12–16GB is preferred for higher resolutions and future-proofing.

RAM

Random-access memory (RAM) acts as a temporary workspace for your computer. While 8 GB is the bare minimum for gaming, 16 GB of DDR4 or DDR5 RAM running at high speed is the current sweet spot. 

For content creators, streamers, or heavy multitaskers, 32 GB provides additional breathing room. Ensure the RAM is dual-channel for better performance, and check your motherboard's compatibility before upgrading.

Cooling

Gaming produces significant heat, especially during long sessions or when running demanding titles. Efficient cooling is essential to maintain performance and prevent thermal throttling. At a minimum, look for multiple case fans. Premium options include tower coolers with heat pipes or liquid all-in-one coolers. 

High-performance rigs may benefit from custom loop liquid cooling, particularly if overclocking the CPU or GPU. Good airflow within the case and high-quality thermal paste can also make a noticeable difference.

Monitors

A responsive monitor improves immersion and reduces input lag. For fast-paced FPS or competitive games, choose a monitor with a 1ms response time and a refresh rate of 144Hz or more. Budget gamers can go for 1080p, but 1440p (QHD) offers a noticeable visual upgrade, while 4K (UHD) delivers ultra-sharp visuals for cinematic gaming. 

Adaptive sync technologies like NVIDIA G-SYNC or AMD FreeSync can reduce screen tearing. If you're using multi-monitor setups, ensure your GPU supports it without frame drops.

Design

Aesthetics matter to many gamers, and modern gaming PCs often reflect personal style. Look for transparent tempered glass panels, RGB lighting (customizable via software), cable management options, and color-matched components. 

Backlit mechanical keyboards, LED-lit mice, and matching gaming chairs can complete the look. While appearance doesn’t affect performance, it does add to the gaming experience and comfort.

Budget Planning and Price Range

When planning your gaming PC in Bangladesh, understanding what features to expect at each price range will set you up for the most optimal option.

Entry-Level (BDT 70,000 – BDT 90,000)

At this budget, expect basic gaming performance suited for casual or competitive games at 1080p resolution with medium settings. Systems typically come with integrated or entry-level separable graphics cards, sufficient RAM, in most cases, around 8GB, and modest storage, usually 256GB SSD. Cooling solutions are standard air cooling. Upgrade potential is limited, but enough for beginners.

Mid-Range (BDT 110,000 – BDT 160,000)

This price range offers solid 1080p high or 1440p medium settings. PCs here usually feature mid-tier dedicated GPUs with considerable ray tracing and cooling components. The best setups would feature a minimum of 32GB RAM, faster SSDs, 500GB at least, and improved cooling options like additional case fans or basic liquid cooling. Expandability options improve with better motherboards and power supplies. Intel 14th Gen Core i5-14400 makes a solid choice in this section.

High-End (BDT 200,000+)

High-end builds support 1440p ultra or 4K gaming with ray tracing enabled and high frame rates. Expect top-tier GPUs with dedicated VRAM, high core-count CPUs, 32 GB+ DDR5 RAM, NVMe SSDs with large capacity and fast speeds, and advanced cooling systems such as custom liquid cooling setups. These PCs offer excellent future-proofing, better aesthetics like RGB lighting, and premium build quality.

Customization vs Pre-built Gaming PC

When considering a gaming PC, one of the biggest decisions is whether to build it yourself or buy a pre-built system. Custom builds offer better value for money, where you can handpick each component to maximize performance within your budget. If you enjoy being curious and creative and don’t mind the time commitment, you will find building your own PC exciting.

Now, buying a pre-built PC has its own set of practical advantages. With a pre-built, you get customer support, warranties, and replacements in case of defective components. All without the risk of build errors or compatibility issues. It also saves hours of research and assembly, making it ideal for those who just want to plug in and play.

Performance lovers can do wonders if they can get their hands on the components they deem powerful and relevant for their dream setup. They can build systems that overplay even the best pre-built options. 

The tradeoff is a slightly higher cost, but some sellers offer fair pricing if bought in bulk. Just ensure you're paying for convenience and not an overpriced brand label. In the end, the right choice depends on how much you value control versus convenience, and how you want to spend your time.

Performance & Benchmarking Tips

When choosing a gaming PC, benchmarking is essential to measure performance. Benchmarks give away frame rates (FPS), load times, and system stability during gaming. Specifically for gamers, special focus should be on the FPS. Because the higher the FPS, the smoother the gameplay. Here are a few ways you can check the benchmark scores of different components:

Reliable Sources: Use trusted benchmarking websites or videos. This helps you understand how CPUs and GPUs perform under different workloads.

Balance CPU and GPU: A strong GPU paired with a weak CPU, or vice versa, can create bottlenecks. And nothing can intimidate your gameplay experience more. Benchmarks reveal if your hardware combo is well matched.

Match Resolution and Settings: Benchmarks vary depending on resolution and graphics settings. Be careful in choosing options that favour your goal. For example, a mid-range GPU may handle 1080p well but struggle with 4 K.

Consider Cooling and Stability: Overheating can throttle performance. Look for benchmarks that include temperature tests to ensure your system’s cooling is adequate for long sessions.

Future-Proofing: Check benchmarks for upcoming games when possible. This helps ensure your PC stays capable longer before needing upgrades.

Choosing the Right Gaming Accessories

Accessories are the secret to enjoyable gameplay. Essential options include a high-DPI gaming mouse, comfortable keyboards, and quality audio or VR headsets. Even though their mostly secondary enhancements, they are not insignificant enough to be overlooked. Especially when the compatibility, maintenance, and support are concerns.

Gaming keyboard

A good gaming keyboard can improve both comfort and reaction time. Look for mechanical switches that match your gaming style. Features like anti-ghosting, N-key rollover, and macro programmability have become mainstream. RGB backlighting adds aesthetic flair and minimal functionality in low-light conditions.

Gaming mouse

If nothing else, a gaming mouse should fit your hand comfortably. Also, it should offer customizable DPI settings for accuracy. Some advanced models include weights for balance, onboard memory for storing profiles. You will also find extra buttons for mapping in-game functions. Look for a high polling rate, maybe 1000Hz or more. Low click latency will help minimize delay.

Gaming mousepad

A high-quality mousepad will add to better sensor accuracy and control. Larger pads are spacious enough to lie beneath both your mouse and keyboard. Soft and textured surfaces provide better mobility and control. Non-slip rubber bases and stitched edges increase durability.

Headset

A good gaming headset can drastically improve spatial awareness and communication. Look for surround sound, noise-canceling microphones, and cushioned ear cups for long-term comfort. Wireless headsets offer freedom of movement, while wired ones avoid latency. Compatibility with audio software like Dolby Atmos or DTS X can enhance immersion further.

Virtual Reality Headsets

VR headsets are trending among gamers for their immersive way to a real-life gaming experience. VR headsets like the Meta Quest, Valve Index, or HTC Vive invite you directly into the graphical world. Ensure your GPU meets the minimum VR requirements. Prepare your setup for additional space and sensors.
