While it certainly is nice to monitor CPU usage, it's ultimately useless to determine bottlenecks as windows likes to assign processor load across several cores and Amdahl's Law and Hyperthreading makes things even more complicated. Short story, CPU usage is useless to determine processor bottlenecks unless you're running a single core without hyperthreading.

GPU Usage, on the other hand, is a lot more informative as a non-99% usage indicates a PCIe/CPU-bottleneck (which with todays CPUs means the same thing: swap processor for better performance.)
