Desktop Computer Guide: From Basic Office Work to Gaming, Components and Budget

In a market flooded with laptops and tablets, the desktop PC remains the undisputed king when it comes to ergonomics, longevity, thermal performance and economic value for every euro invested. No other form factor lets you repair or upgrade individual parts for a decade without having to replace the entire machine.

Whether you’re looking for a quiet machine to work from home with spreadsheets and video calls, or you aspire to build a battle station to squeeze the most demanding video games at 4K resolution, understanding the role of each component is the key to not wasting your budget.

1. The three configuration tiers based on your needs

Tier 1: Office work, smooth browsing and remote work (€350 – €550)

For administrative tasks, studying, invoicing and media consumption, a dedicated graphics card isn’t needed. The key lies in a processor with modern integrated graphics (APU):

• Processor (CPU): AMD Ryzen 5 5600G / 8500G or Intel Core i3-13100 / i5-12400. They feature 4 to 6 fast cores and integrated graphics chips capable of driving two 4K monitors at 60Hz without breaking a sweat.
• RAM: 16 GB DDR4 or DDR5 in a dual-channel configuration (two 8 GB modules). This guarantees absolute smoothness with dozens of browser tabs open simultaneously.
• Storage: A 500 GB or 1 TB PCIe NVMe SSD. The operating system boots in 7 seconds and programs open instantly.
• Form factor: Compact Micro-ATX towers or low-power Mini-PCs that use less electricity than an incandescent light bulb (25W – 50W under load).

Tier 2: Heavy multitasking, multimedia editing and casual gaming (€700 – €1,100)

The most balanced tier for versatile users who edit photos in Lightroom, render the occasional video or game at 1080p resolution with high graphics settings:

• CPU: AMD Ryzen 5 7600 or Intel Core i5-13400F / 14400F.
• Dedicated graphics card: Nvidia GeForce RTX 4060 (8 GB) or AMD Radeon RX 7600 XT (16 GB). They let you game at more than 80-100 FPS at 1080p and accelerate video export tasks via the GPU.
• RAM: 32 GB DDR5 at 6,000 MHz. Plenty of room for editing and intensive multitasking.
• Power supply: 600W to 650W with 80 Plus Bronze or Gold certification from reputable brands (Corsair, Seasonic, be quiet!).

Tier 3: High-refresh-rate gaming at 1440p / 4K resolution (€1,300 – €2,200)

For enthusiasts seeking maximum visual fidelity, Ray Tracing and competitive refresh rates (144Hz to 240Hz):

• CPU for pure gaming: AMD Ryzen 7 7800X3D (the undisputed gaming processor thanks to its massive 3D V-Cache) or Intel Core i7-14700K.
• Graphics card: Nvidia GeForce RTX 4070 Ti Super / RTX 4080 Super or AMD Radeon RX 7900 XT. They deliver massive power for gaming at 1440p ultra and 4K with DLSS 3 / FSR technologies enabled.
• Cooling and chassis: Large dual-tower air coolers (Thermalright Peerless Assassin / Noctua NH-D15) or 240/360 mm AIO liquid cooling inside cases with a mesh front panel (mesh) to ensure constant airflow.
• Power supply: 750W to 850W 80 Plus Gold with a native PCIe 5.0 connector (12VHPWR).

2. Comparison table of recommended components by tier

«The most beautiful thing about a desktop PC is that it never dies: when a part falls short four or five years down the line, you just swap out the graphics card or the memory for a fraction of the cost and you have a new machine for another five years.»
