Build a 240FPS Competitive Esports PC for Under £300 (Valorant, CS2 & Fortnite)

In competitive esports titles like Valorant, Counter-Strike 2, Fortnite, and Apex Legends, graphical fidelity takes a backseat to raw frame throughput and frame time consistency. When aiming for 144Hz, 180Hz, or 240Hz monitor refresh rates, you do not need a four-figure rig featuring an RTX 4080.
With careful component selection across the UK second-hand market, you can assemble a lightning-fast, ultra-low-latency esports desktop for under £300 total. In this complete build guide, we provide a verified shopping list with actual UK sold prices, assembly instructions, and BIOS/in-game optimisations to maintain stable triple-digit FPS.

3. Esports Optimization Tips
- Enable XMP in BIOS: Operating dual-channel DDR4 memory at 3200MHz CL16 instead of stock 2133MHz JEDEC speeds lifts 1% low frame rates by upwards of 20% in Counter-Strike 2.
- NVIDIA Reflex Low Latency: Turn Reflex to "On + Boost" in the game menu to lower rendering queue latency to under 12ms.
