The components market in 2025 demonstrates a shift towards energy efficiency, compactness, and integration of artificial intelligence into the user experience. Building a gaming PC is not just about selecting powerful components, but about the optimal combination of computational capabilities, thermal balance, and future-proof interfaces. Choosing each component requires a comprehensive approach: considering price, performance, compatibility, and future upgradability.
Processor: the core of gaming potential
Modern AAA games in 2025 rely on multi-threaded performance. When assembling a gaming PC capable of smoothly running Baldur’s Gate IV, Cyberpunk 2077 Enhanced Edition, or Microsoft Flight Simulator 2025, start with selecting the processor.
At the peak of popularity are Intel Core 15th generation chips (e.g., i7-15700KF with 16 threads and 5.4 GHz boost) and AMD Ryzen 9000 series (Ryzen 7 9800X, 12 threads, 3D V-Cache). The former is a choice for those focusing on high frequency, while the latter is for streamers and multitasking.

Direct access to DDR5-7200 RAM, intelligent thread distribution, and stable operation at 90% load are the minimum requirements from a CPU in 2025. It’s important to note that gaming performance depends not on brand prestige, but on specific tests in the right games at the right settings. Always compare based on FPS, input delay, and temperature.
Graphics Card: assembling a gaming PC in 2025
Building a gaming PC with maximum graphics in 2025 requires a graphics card like the GeForce RTX 5090 or Radeon RX 8900XT. The former provides ray tracing in 4K at 100+ FPS, while the latter offers high stability and slightly lower TDP (up to 320W compared to NVIDIA’s 450W).
The introduction of NVIDIA DLSS 4.1 and AMD FSR 3.2 allows for up to a 2.5x increase in FPS with minimal quality loss. This is particularly important for 240 Hz monitors. Don’t chase the flagship if your screen resolution is 1080p; in that case, RTX 5080 or RX 8800XL will handle most titles.
RAM: high-speed buffer
In 2025, DDR5 has completely replaced DDR4. To build a gaming PC capable of running smoothly even with OBS, Chrome, and Discord open in the background, you need at least 32GB of DDR5-7200 with CL36. Games like Starfield 2 or Red Dead Redemption III require 16 to 24GB of active memory. Opting for two 16GB modules is preferable for dual-channel mode. Brands like G.Skill Trident Z5 or Kingston Fury Beast Dominator offer an optimal balance of temperature and error frequency.
Storage: loading speed and capacity
To build a gaming PC with fast boot times and instant level loading, you need an NVMe 4.0 SSD. The minimum capacity should be 1TB, preferably with a PCIe Gen4x4 or even Gen5 interface (e.g., Samsung 990 PRO or WD Black SN850X).
Games with sizes of 150–250GB have become the norm. Titles like Call of Duty 2025, The Last of Us Part II Remastered, GTA VI require speeds of at least 5000 MB/s for reading; otherwise, loading times will resemble the HDD era. Adding a second 2TB SSD for archives and streaming projects is a must for streamers and creators.
Motherboard: the foundation of reliability
To build a gaming PC where all components work seamlessly, choose the right motherboard. For LGA 1851, models like ASUS ROG Z790 Hero II or MSI MEG Z790 ACE MAX are suitable. For AM5, consider Gigabyte Aorus X670E Master or ASUS TUF Gaming B650-Plus Wi-Fi.
Having support for PCIe 5.0, at least four M.2 slots, stable power delivery, and a good cooling system (including VRM radiators) has become essential. Additionally, built-in Wi-Fi 6E and 2.5G Ethernet are important; even minimal ping matters in games.
Cooling: temperature comfort
To build a gaming PC with longevity, install a well-thought-out cooling system. A 360mm AIO cooler with ARGB lighting, such as the Arctic Liquid Freezer III or NZXT Kraken Elite 360 RGB, is currently popular. An alternative is a tower cooler like the Noctua NH-D15 Chromax Black (if the case allows for its height). Don’t skimp on case ventilation. Proper airflow and separate streams for the CPU and GPU ensure stable operation even in 35-degree heat.
Case and Power Supply: assembling a gaming PC in 2025
The case should accommodate the components’ dimensions and provide proper airflow. Popular models include Fractal Design North XL, Lian Li O11 Dynamic EVO XL, NZXT H9 Flow. To build a gaming PC without temperature issues, choose a case with at least three 140mm fans.
The power supply should be a minimum of 850W, preferably with an 80+ Gold or Platinum certification. Seasonic Focus GX-1000 or Corsair RM1000x are ideal for configurations with RTX 5090.
Monitor, Peripherals, and Software
To build a gaming PC and start playing immediately, consider the monitor. Gaming models in 2025: 32” 2K 240Hz IPS or 27” 4K 144Hz OLED (e.g., ASUS ROG Swift PG32UQXR or LG UltraGear OLED 27GR95QE).
For the keyboard, opt for a mechanical one with optical switches (Razer Huntsman V3, SteelSeries Apex Pro 2025). The mouse should have a sensor with at least 30,000 DPI (Logitech G502X Plus, Razer DeathAdder V3 Pro). The operating system should be Windows 11 Pro with up-to-date drivers, customized Game Mode, temperature monitoring, and BIOS updates.
