With GPUs hitting ÂŁ1,200 and CPUs topping ÂŁ400, new-gen builds have priced many UK consumers out of the market. Instead, the community thrives on second-hand hardware - a culture rooted in affordability, value cycles, and sustainability through reuse and right-to-repair.
CoreWeave and OpenAI have expanded their partnership with a new $6.5B contract, bringing the total to $22.4B in 2025. The deal supports OpenAI’s Stargate project, relies heavily on Nvidia hardware, and raises questions about concentration and regulatory scrutiny in AI infrastructure.
Nvidia’s $100B OpenAI deal promises 10GW of AI compute power by 2026. The company insists GPU supply for gamers won’t suffer, but with such massive demand on the horizon, many fear a repeat of past shortages. Is this the start of an AI-first Nvidia era, and what does it mean for PC gaming?
