Intel Celeron J4125 is good for gaming. It's a low-power, budget-oriented processor primarily designed for basic computing tasks, such as web browsing, document editing, and media consumption. While it can handle some older or less demanding games at lower settings, it lacks the processing power and dedicated graphics capabilities needed for modern, resource-intensive gaming. For gaming purposes, it's advisable to opt for a more powerful CPU with dedicated graphics or an integrated GPU like Intel Iris Xe or AMD Vega, found in higher-tier processors.
