There isn't necessarily anything unusual about high CPU usage, as it strongly depends on what PD (and also your computer) is doing at the time.
Did you only notice the issue when you were producing a video, or were shadow files still being generated while you were editing? Both of those situations can cause very high CPU demands. Same with 4K (or higher) resolution clips, depending on what GPU hardware you have installed and whether you're using hardware acceleration or not.
If you're using shadow files, the best thing to do is to let PD finish making them before doing any serious editing. You'll see the yellow icons on the Media Library icons turn green as each clip is processed. The same goes for temporary slowdowns, let PD sit for a minute and see if/how much the CPU load drops. Make a note of what you were just doing and see if there's a correlation when you start doing that again.
Post back with more details, especially the ouput profile you were producing to if that's when you noticed the issue, and we can try to assist you with specific suggestions. It would also help if you followed the steps in the Read Me Before Posting sticky thread so we can see the DxDiag results.
