At Geeks Callout London, we recently completed a bespoke high-performance gaming PC build for a customer based in Chelsea (SW3), London. The client’s requirement was clear: a powerful, reliable system capable of running Call of Duty and other heavy-duty, modern first-person shooter games smoothly at high and ultra FPS settings, without overheating, lagging or performance drops.
From initial consultation to final delivery, this custom-built gaming PC was designed, assembled, tested, and fully optimised in just 3 days, highlighting our expertise in fast turnaround without compromising on quality.
Understanding the Customer’s Gaming Requirements
Our Chelsea customer wanted a system that could deliver:
With these goals in mind, our engineers carefully selected each component to ensure long-term reliability, performance, and upgrade flexibility.
Premium Components Used in This Custom Gaming PC
MSI Suprim NVIDIA RTX 5080 – 16GB Graphics Card
To handle graphically demanding games with ease, we installed the MSI Suprim RTX 5080 16GB graphics card. This top-tier GPU delivers exceptional performance, advanced ray tracing, and smooth gameplay even under extreme graphical loads, making it ideal for competitive and immersive gaming.
Intel Core i9-14900K (14th Generation Processor)
Powering the system is the Intel Core i9-14900K, one of the most powerful processors available. This CPU ensures outstanding performance for gaming, multitasking, and background processes, keeping gameplay smooth even during intensive sessions.
Water Liquid Cooling, Corsair Nautilus 360 RS ARGB
To maintain safe temperatures and consistent performance, we installed the Corsair Nautilus 360 RS ARGB water liquid cooling system. This high-performance liquid cooler keeps the processor cool under heavyload, reduces thermal throttling, and adds a premium ARGB aesthetic to the build.
32GB Corsair RAM – High-Speed Memory
We installed 32GB of Corsair high-performance RAM, ensuring the system has more than enough memory to support all components working together seamlessly. This allows for smooth multitasking, faster game loading, and improved overall system responsiveness, especially when running modern games and background applications simultaneously.
MSI Z790 Gaming Plus WiFi Motherboard
The build is based on the MSI Z790 Gaming Plus WiFi motherboard, offering excellent stability, fast connectivity, and full compatibility with the latest Intel processors, high-speed RAM, and next-generation graphics cards.
Excellent Airflow with Multiple Cooling Fans
To further enhance cooling, we installed multiple high-quality case fans throughout the system. Combined with the spacious Fractal Design XL E-ATX case, this setup ensures very high airflow, allowing fresh air to circulate efficiently and heat to escape quickly.
Storage Setup – Speed and Capacity Combined
Modern games require both speed and space, so we installed a dual-storage configuration:
This setup gives the customer plenty of fast, reliable storage for years to come.
Full Stress Testing & Performance Validation
Before delivery, the gaming PC went through extensive stress testing to ensure complete stability and reliability. We used industry-standard tools including:
All components performed perfectly under sustained heavy loads, confirming the PC was fully stabilised and gaming-ready. For transparency, we also captured screenshots and photos as evidence of performance and build quality.
Built, Tested & Delivered in Just 3 Days
Despite using premium components and conducting thorough testing, the entire build was completed within three days. The customer received a fully optimised, plug-and-play gaming PC, ready to enjoy immediately.
