Custom Built Computers Montreal
Montreal PC Support builds custom computers for clients who need more than a basic off-the-shelf desktop. A properly planned custom system can deliver better performance, cleaner airflow, better upgrade options, quieter operation and a longer useful life.
Modern Hardware Options
We can plan custom builds around current gaming and workstation hardware, including AMD Ryzen X3D processors, Intel Core Ultra desktop platforms, NVIDIA GeForce RTX 50 Series graphics cards and AMD Radeon RX 9000 Series options. Hardware availability and pricing can change, so every recommendation is confirmed before ordering parts.
Gaming PC Builder Montreal
Montreal PC Support builds custom gaming PCs for competitive esports, 1440p gaming, ultrawide monitors, 4K gaming, streaming and high-refresh-rate setups. A gaming system should be balanced: the processor, graphics card, memory, motherboard, power supply, storage and cooling system must work together. A very expensive graphics card can still perform poorly if the case airflow is weak, the power supply is under-sized, the CPU bottlenecks the system, the storage is slow or the BIOS and drivers are not configured correctly.
For gaming-focused systems, many clients ask about AMD Ryzen X3D processors because they are known for strong gaming performance and low latency. Ryzen 7 9800X3D and Ryzen 9 9950X3D systems can be excellent choices depending on whether the build is strictly for gaming or also needs productivity performance. Intel Core Ultra desktop processors may also be suitable for gaming, streaming and professional workloads depending on the platform and software requirements.
For graphics cards, we can plan systems around NVIDIA GeForce RTX 5070, RTX 5070 Ti, RTX 5080 and RTX 5090 options, or AMD Radeon RX 9070 XT options depending on your budget, monitor resolution and gaming goals. We do not recommend parts based only on marketing names. We look at the games you play, the monitor you use, the frame-rate target, cooling requirements, future upgrades and the total budget.
Workstation Computer Builder Montreal
Not every custom computer is a gaming PC. Many clients need a reliable workstation for professional work. We build workstation computers for Adobe Premiere Pro, DaVinci Resolve, After Effects, Photoshop, Lightroom, Blender, AutoCAD, Revit, SolidWorks, Fusion 360, engineering applications, architecture, accounting, office workloads and business environments.
A video editing workstation needs fast storage, enough RAM, a suitable GPU, a strong CPU and a backup strategy. A CAD workstation may need stability, professional software compatibility, strong single-thread performance and reliable cooling. A business workstation may prioritize reliability, low noise, quick serviceability and data protection. We choose parts based on the actual workload instead of building every workstation like a gaming PC.
Custom AI Computers Montreal
AI workstations require careful planning because GPU memory, power delivery, cooling and storage speed can matter as much as raw CPU performance. We can build AI-ready computers for local AI tools, Stable Diffusion, LLM experimentation, GPU rendering, data processing and professional creative workflows. These systems may require high VRAM GPUs, large memory capacity, fast NVMe storage and a power supply designed for demanding graphics cards.
For clients working with AI, rendering or 3D workloads, we discuss whether the system should prioritize GPU performance, VRAM, CPU cores, memory capacity, storage throughput or noise control. The goal is to build a stable and practical workstation, not just a system with expensive parts.
Modern CPUs for Custom Computers
The CPU affects gaming performance, rendering speed, compiling, streaming, multitasking, power draw, thermals and future upgrade options. When we plan a custom build, we consider whether the system is mainly for gaming, content creation, business work, CAD, AI, virtual machines or a mix of those tasks. The right CPU choice also affects motherboard selection, RAM support, cooler requirements and case airflow.
Graphics Cards for Gaming, AI and Creative Work
The graphics card is often the most expensive part of a gaming or workstation build. NVIDIA GeForce RTX cards are popular for gaming, ray tracing, DLSS, CUDA-based workloads, AI tools, video acceleration and creative applications. AMD Radeon cards can also be excellent options depending on gaming goals, price, availability and software needs.
A high-end GPU requires more than just a PCIe slot. We verify case clearance, airflow, power supply quality, connector requirements, thermal performance and motherboard layout. Large GPUs can block access to slots, affect cable management or run hotter in cases with poor airflow. For professional systems, we also consider VRAM capacity and long-term stability.
Water Cooled Gaming PCs Montreal
Thermal design is one of the biggest differences between a clean professional build and a rushed assembly. A custom computer may use air cooling, an AIO liquid cooler or a custom liquid cooling loop. Air cooling is simple, reliable and easy to maintain. AIO liquid cooling can provide strong cooling performance and a clean look for many high-performance CPUs. Custom liquid cooling can look impressive and offer advanced thermal possibilities, but it also requires more planning, maintenance and budget.
We install and configure cooling systems based on the parts, case, airflow path and user expectations. Fan orientation, radiator placement, cable management and dust control all matter. A powerful gaming PC or workstation should not only look good; it should run reliably under real load.
Storage, Memory and Power Supply Planning
A custom computer should not be judged only by the CPU and GPU. Storage, memory and power supply quality are equally important. We often recommend fast NVMe SSD storage for operating systems, applications and active projects. Larger secondary SSDs or hard drives can be added for storage, backups or media libraries.
Memory capacity depends on the workload. A gaming PC may perform well with 32GB of RAM, while video editing, large Photoshop projects, CAD assemblies, virtual machines, AI workflows and professional applications may require 64GB, 96GB, 128GB or more. The power supply is another area where cheap choices can create expensive problems, especially with high-end graphics cards.

Our Custom Build Process
Our custom build process begins with a discussion about what the computer needs to do. We ask about the budget, software, games, monitor resolution, storage needs, noise preferences, aesthetics, upgrade goals and timeline. From there, we create a parts plan and explain the reasoning behind the recommendations. The client can approve the configuration before parts are ordered or assembled.
After the parts are selected, we assemble the computer carefully with attention to cable management, airflow, component fit, BIOS configuration, operating system installation and driver setup. We test the system for stability, temperatures, storage health, memory behavior and overall performance.
