The GeekaPC Sim Racing 'Ultra' is our flagship build designed for sim racers who want the absolute best - capable of powering super ultrawide and multi-monitor setups at maximum detail with no compromises.
At the heart of the build sits the AMD Ryzen 9 9950X3D, AMD's most powerful consumer processor. Sixteen Zen 5 cores, 128MB of stacked 3D V-Cache, and boost clocks up to 5.7GHz make this the definitive sim racing CPU - eliminating bottlenecks entirely in even the most demanding racing environments, while delivering the additional core headroom for streaming, content creation, or anything else you want to run alongside your session.
Paired with 32GB of Kingston Fury Beast RGB DDR5 running at 6000MT/s and a Biwin Black Opal NVMe SSD with read speeds up to 7400MB/s, you'll benefit from rapid load times and a system that responds instantly from boot to track.
Graphics are handled by the NVIDIA GeForce RTX 5090, the most powerful consumer GPU ever made. With 32GB of GDDR7 memory across a 512-bit memory bus and DLSS 4 Multi Frame Generation support, the RTX 5090 is one of the only GPUs capable of driving a triple 4K display setup in sim racing titles at genuinely high frame rates. At a combined resolution of 11520x2160, most hardware struggles - the 5090 does not.
The entire build is assembled inside the Montech King 95 Pro Black, bringing the same dual-chamber design with curved 4mm tempered glass panels in an all-black finish. Six pre-installed ARGB PWM fans contrast brilliantly against the black interior, giving the Ultra build a look that matches its performance.
Every system in the full GeekaPC Sim Racing lineup is fully tested within the most popular sim racing titles before it leaves our hands. GeekaPC are also official sponsors of the Driven racing team, entered into the 2025 Ferrari Challenge series - providing the complete sim racing setup, including PC, monitors, wheel and pedals, to help driver John train for real-world racing at iconic circuits like Silverstone and Brands Hatch.
CPU (Processor): AMD Ryzen 9 9950X3D
The Ryzen 9 9950X3D is AMD's most powerful consumer processor, combining sixteen Zen 5 cores with 128MB of stacked 3D V-Cache for the absolute best CPU performance available in a sim racing build. Its massive cache eliminates CPU bottlenecks entirely in even the most complex racing environments, while the additional cores deliver headroom for streaming, content creation, and multitasking alongside your sim titles.

CPU Cooler: ARCTIC Liquid Freezer III Pro 360
The ARCTIC Liquid Freezer III Pro 360 is one of the highest-performing AIO coolers available, and a well-matched partner for the 9950X3D's 170W TDP. Its 38mm thick radiator, three high-static-pressure P12 Pro fans, and built-in VRM fan ensure the processor runs cool and controlled under sustained full-load conditions - essential for maintaining peak boost clocks across all sixteen cores.

Motherboard: Gigabyte B850 Eagle WiFi6E
The Gigabyte B850 Eagle WiFi6E is a well-rounded AM5 motherboard with PCIe 5.0, Wi-Fi 6E, and AMD EXPO memory support. Its clean power delivery handles the 9950X3D's 170W TDP with ease, and the B850 chipset provides everything needed for a high-performance Ultra sim racing build without unnecessary cost overhead.

RAM: Kingston Fury Beast RGB 6000MT/s CL36
Kingston Fury Beast RGB DDR5 at 6000 MT/s CL36 remains the performance sweet spot on the AM5 platform, sitting at the optimal frequency for AMD EXPO-tuned throughput. Fast and reliable, it pairs well with the 9950X3D and complements the RGB lighting inside the King 95 Pro Black's glass panels.

SSD: Biwin Black Opal NV7400
The Biwin Black Opal NV7400 is a high-speed PCIe 4.0 NVMe SSD delivering read speeds up to 7400 MB/s. It ensures rapid game loading and responsive system performance across all sim racing titles, keeping you in the action rather than waiting on loading screens.

GPU (Graphics Card): NVIDIA GeForce RTX 5090
The NVIDIA GeForce RTX 5090 is the most powerful consumer GPU ever made, delivering unmatched performance across every resolution and every sim title. With 32GB of GDDR7 memory and DLSS 4 Multi Frame Generation, it drives the Ultra rig's display at maximum detail and frame rates with headroom to spare - whether that's a super ultrawide at 5120x1440 or a triple-screen setup at a later date.
Case: Montech King 95 Pro Black
The Montech King 95 Pro Black is the blacked-out variant of the King 95 Pro, bringing the same stunning dual-chamber design with curved 4mm tempered glass panels but finished in an all-black colourway that gives the Ultra build a sleek, premium aesthetic. Six pre-installed ARGB PWM fans and a 10-port fan hub come included, with the RGB lighting contrasting beautifully against the black interior.
PSU: Corsair RM1000e
The Corsair RM1000e is a fully modular 80 PLUS Gold power supply delivering 1000W of clean, stable output - the right choice for the RTX 5090's substantial power demands. With ATX 3.1 compliance, near-silent operation at low loads, and generous headroom above the system's estimated draw, it gives the Ultra build the solid power foundation it deserves.
PSU Capacity vs Estimated System Draw
The RM1000e is running closer to capacity with the RTX 5090 and Ryzen 9 9950X3D, which is expected for a flagship build. The 1000W rating provides the headroom needed for safe, stable operation under sustained full-load conditions.
Operating System: Windows 11
All of our systems come preinstalled with an activated copy of Windows 11 set to the 'Out of Box Experience'. This allows you to set the PC back up to your liking.
