idk why you think it isnt good for gaming, honestly the GPU is much more of a concern when getting into which is better for game preformance.....
i5-6400 is not a good CPU for gaming, it's worse than lowbudget AMD A8-7600 an 70 EUR APU, which is made for low budget Office-PCs: http://cpuboss.com/cpus/Intel-Core-i5-6400-vs-AMD-A8-7600
Intel Core i5 6400 or Intel Boxed Core I5-6600K? Which one is best for gaming? Can you tell me the Pros and Cons?
