The Components: What Does What
CPU (Processor)
The “brain” of the PC. For gaming, 6-8 cores are sufficient. In 2026: AMD Ryzen 9000X3D or Intel Arrow Lake-S.
GPU (Graphics Card)
The most important gaming component. Determines FPS and resolution. NVIDIA RTX 50-series or AMD RX 9000.
RAM (Memory)
DDR5 is now standard. 32GB for gaming, 64GB if you stream/edit simultaneously.
SSD (Storage)
NVMe Gen5 for boot drive (1-2TB). Loading times virtually zero. Speeds up to 14 GB/s.

CPU: AMD vs Intel 2026
🆚 Processor Comparison
| CPU | Cores/Threads | Gaming Performance | Price |
|---|---|---|---|
| AMD Ryzen 7 9800X3D | 8/16 | 🥇 #1 Gaming CPU (3D V-Cache) | ~€480 |
| AMD Ryzen 5 9600X3D | 6/12 | 🥈 Top value gaming | ~€300 |
| Intel Core Ultra 9 265K | 8P+16E/32T | 🥉 Very powerful all-around | ~€590 |
| Intel Core Ultra 5 245K | 6P+8E/20T | Excellent mid-range | ~€330 |
| AMD Ryzen 5 9600X | 6/12 | Budget champion | ~€220 |
💡 Pro Tip
If the PC is primarily for gaming, go AMD X3D — the 3D V-Cache delivers 15-25% more FPS in demanding titles. If you also do productivity work (rendering, compiling), Intel Arrow Lake is worth considering.

Assembly Steps
🔧 Build Guide
- 1. Preparation: Anti-static wristband, magnetic screwdriver, good lighting
- 2. CPU → Motherboard: Install CPU first (golden triangle / notch alignment)
- 3. RAM → Motherboard: Correct slots (A2/B2 for dual channel)
- 4. M.2 SSD: Screw into M.2 slot before the motherboard goes in the case
- 5. Cooler: Apply thermal paste (rice-grain size dot) and secure
- 6. Motherboard → Case: Screw with standoffs, connect front panel
- 7. GPU: x16 PCIe slot, connect power cables
- 8. PSU → Cables: Connect 24pin, 8pin CPU, GPU power
- 9. Cable Management: Route cables behind the tray
- 10. Power On: First boot → BIOS → Windows/Linux install
Final Verdict
Building a custom PC in 2026 is easier and more rewarding than ever. DDR5 and SSD prices have dropped dramatically, new CPUs and GPUs deliver a massive performance leap, and assembly is more straightforward. Start with the budget build if you’re a beginner — you can always upgrade component-by-component later.
