Building My Power-User Workstation: A Custom PC for AI, Image Generation, and Gaming
For years, I’ve built and upgraded computers to match my evolving needs, but this time, I wanted something special—a machine that could handle intensive workloads while staying within a reasonable budget. My goal was to create a powerful yet cost-effective workstation, optimized for running small language models (under 16B parameters), image generation tools like Stable Diffusion, and, of course, the occasional game.
Why Build a Custom PC?
Prebuilt machines often come with unnecessary bloat, proprietary components, and price premiums that make upgrading difficult. I wanted full control over my hardware—no compromises on performance, cooling, or expandability. By carefully selecting each component, I ensured my system was fine-tuned for AI workloads and creative applications without breaking the bank.
The Build: Balancing Power and Efficiency
After extensive research and benchmarking, I settled on the following components:
- CPU: AMD Ryzen 9 7900X – A 12-core, 24-thread beast that delivers excellent multi-threaded performance without the power draw of the 7950X.
- Motherboard: MSI MAG X670E – Packed with PCIe 5.0 support and robust VRMs for stability and future-proofing.
- Memory: CORSAIR VENGEANCE DDR5 64GB (2x32GB) 6000MHz CL30 AMD EXPO – Optimized for high-speed AI workloads and memory-intensive applications.
- Storage: WD_BLACK 2TB SN850X NVMe SSD – Ultra-fast read/write speeds for quick data access and caching models efficiently.
- GPU: ASUS NVIDIA GeForce RTX 4070 Ti SUPER OC 16GB – A solid choice for AI inference tasks, image generation, and gaming at high resolutions.
- Case: CORSAIR 3500X ARGB Mid-Tower ATX – Great airflow, spacious, and aesthetically pleasing.
- Power Supply: Corsair HX850 – Reliable and efficient with >100 watts of headroom to spare.
- Cooling:
- Noctua NH-D15 chromax – Ensuring the CPU stays cool and quiet, even under full load.
- Noctua NF-A12x25 PWM chromax (120mm rear fan) – Helps efficiently exhaust heat from the CPU cooler.
- 3x CORSAIR RS120 ARGB Fans – Included with the case, providing excellent airflow and RGB aesthetics.
Performance Tweaks & Optimization
With hardware in place, fine-tuning was the next step.
- Overclocking & Undervolting: Adjusting CPU voltages and using Precision Boost Overdrive (PBO) to maximize efficiency without excessive heat.
- Memory Tuning: Enabling AMD EXPO for optimal RAM performance, ensuring AI models and rendering tasks run smoothly.
- Cooling & Airflow: Configuring fan curves to keep the system cool while maintaining quiet operation.
AI & Image Generation Workloads
One of the main reasons for this build was to run small LLMs (under 16B parameters using GGUF models with quantization) locally, allowing me to experiment with AI without relying on cloud services. Additionally, I use Stable Diffusion for generating high-quality AI images. Thanks to the GPU’s CUDA cores and Tensor cores, image processing speeds are fantastic, and the system handles multi-tasking with ease.
Gaming & Everyday Use
Though gaming wasn’t the primary focus, this system still delivers top-tier performance in modern titles. With high-refresh-rate gaming in mind, the 4070 Ti Super ensures smooth frame rates in AAA games at 1440p and even 4K. The NVMe storage significantly reduces load times, making the overall experience seamless.
Final Thoughts
This workstation strikes the perfect balance between power and efficiency, offering high performance for AI tasks, image generation, and gaming, all while staying within budget. It’s been an exciting project, and I’m thrilled with how well it performs. If you’re considering a similar build or need help optimizing yours, feel free to reach out!
