If you've done some research, you probably heard of AMD driver overhead. I won't go into details, but basically, AMD GPUs tend to get bottlenecked by AMD CPUs. The result is lots of microstuttering which otherwise wouldn't happen with the same card and an Intel equivalent of the CPU you're using. However, seeing as it's a budget build, you can't do better than that. Even though Intel CPUs offer better performance, AMD is the king of budget builds since it offers a much better price to performance ratio.
