When it comes to choosing the best processor for gaming, it depends on your budget and the specific gaming needs. The Intel Core i5 12400f and the AMD Ryzen 3600X are both good options, with the Ryzen 3600X offering slightly better performance. However, the Ryzen 3600X is also more expensive, so if you are on a budget, the Core i5 12400f may be the better option. Ultimately, it is up to you to decide which processor is the best fit for your gaming needs.
