How to choose a gaming PC?
Not sure how to choose a gaming PC that matches your needs and budget? You're not alone. Choosing a gaming computer can be confusing – dozens of models, hundreds of component combinations and endless discussions on forums. In this guide, we'll show you how to choose a gaming PC step by step, what to focus on and which mistakes to avoid. Whether you're looking for the best gaming PC for 4K gaming or a reasonably priced system for e-sports, this guide will help you.
How to choose a gaming PC: The essential questions
Before you start browsing, answer a few key questions. Choosing the right PC based on its specifications starts with understanding your own needs.
1. What games do you want to play?
Different games have different requirements. E-sports titles (CS2, Valorant, League of Legends) run smoothly even on less powerful hardware. Modern AAA games (Cyberpunk, Alan Wake 2, GTA VI) require significantly more performance. Consider what kind of gaming PC you actually need.
2. What resolution do you want to play at?
-
Full HD (1080p) – the least demanding, a mid-range system is sufficient
-
1440p (QHD) – the sweet spot, requires a more powerful GPU
-
4K (UHD) – the most demanding, requiring a high-end system
3. What is your budget?
Your budget determines what kind of gaming PC you can afford. The good news is that you can get a quality gaming PC even on a limited budget. At HelloComp, you'll find everything from entry-level gaming PCs to extreme gaming machines costing more than CZK 200,000.
4. Do you plan to use it for anything else?
Streaming, video editing, graphics work – all of these affect how you should choose your PC configuration. For multitasking, you'll need more RAM and a more powerful processor.
Choosing a PC by specifications: What to focus on
When deciding how to choose a PC, focus on four key components. These determine what your gaming computer can handle.
Graphics card (GPU)
The graphics card is the most important component for gaming. It determines the resolution and detail settings at which you'll be able to play. When choosing one, focus on:
-
Performance at your target resolution – different GPUs are suitable for Full HD and 4K
-
VRAM capacity – modern games require increasingly more video memory
-
Support for modern technologies – Ray Tracing, DLSS (NVIDIA) or FSR (AMD)
NVIDIA GeForce and AMD Radeon are the two main choices. Both brands offer quality products across different price ranges.
Processor (CPU)
The processor is the brain of the computer. Both single-core performance and the number of cores are important for gaming. As a basic rule:
-
E-sports and Full HD – an Intel Core i5 or AMD Ryzen 5 is sufficient
-
1440p and streaming – Intel Core i7 or AMD Ryzen 7
-
4K and professional work – Intel Core i9 or AMD Ryzen 9
Memory (RAM)
RAM affects smooth performance when multitasking. For gaming:
-
16 GB – minimum for modern games
-
32 GB – ideal for demanding gamers, streamers and content creators
-
64 GB+ – for professional video and 3D work
DDR5 offers higher performance, while DDR4 offers a better price-to-performance ratio. The memory type (DDR4 vs DDR5) depends on the platform. For example, motherboards with an AM4 socket do not support the latest DDR5 memory, while the newer AM5 platform does.
Storage (SSD)
An SSD is standard today. It ensures fast system startup and game loading. Modern games can take up tens or even hundreds of GB, so choose:
-
512 GB – absolute minimum
-
1 TB – a sensible starting point
-
2 TB+ – for a large game library
An NVMe SSD is faster than a SATA SSD, and the price difference is minimal.
How to choose a gaming PC based on your budget
How do you choose a PC if you're not sure how much to invest? This general overview will help:
-
Up to CZK 15,000: Full HD resolution, typically suitable for e-sports and older games.
-
Up to CZK 20,000: Full HD resolution, suitable for modern games at medium settings.
-
Up to CZK 30,000: Full HD / 1440p resolution, ideal for modern games at high settings.
-
Up to CZK 40,000: 1440p resolution, designed for AAA games at ultra settings and streaming.
-
Up to CZK 60,000: 4K resolution, suitable for maximum settings and professional use.
Each category offers the best gaming PC for the given budget. All HelloComp systems are designed with an emphasis on an ideal price-to-performance ratio. For uncompromising top-tier performance, systems costing more than CZK 100,000 are also available.
The most common mistakes when choosing a gaming PC
When deciding how to choose a gaming PC, avoid these mistakes:
-
Unbalanced configuration – an expensive graphics card paired with a cheap processor (or vice versa) means money wasted
-
Underpowered power supply – a poor-quality PSU can damage components or cause instability
-
Too little RAM – 8 GB is no longer enough; choose at least 16 GB
-
Small SSD – 256 GB fills up quickly, so think ahead
-
Ignoring cooling – an overheating computer throttles and loses performance
HelloComp systems are designed to be balanced, ensuring that all components work optimally together.
Why buy a pre-built PC instead of building your own

-
Guaranteed compatibility – all components are verified and matched with each other
-
Professional assembly – built by experienced technicians
-
Testing – every computer undergoes stress testing before shipping
-
Warranty – a single warranty covering the entire system with Czech-based service
-
Upgrade options – RAM, SSD, GPU and CPU can be upgraded according to your needs
In addition, every product features an FPS calculator that shows you real-world performance in specific games. No guessing – just facts.
