Components that are years generationally behind. Example: 3700x CPU will bottleneck with a 4090 gpu. You need Components that are relatively close in terms of generation. A CPU being 1 year behind a GPU isn't an issue, it's when you put a newer GPU or CPU with something like 3 years older or more than the new component your installing is when you'll run into the bottlenecks, also consider the game being played. You might not see a bottleneck with older and newer parts together running older games but running new titles on a PC with an old CPU and new GPU, you could see issues.
so it is bad idea putting Ryzen 7 5700x on those specs ?
