Is My GPU Usage Normal?

[saltbox23k]

Hello,

 

So basically for the past month I have been getting random frame drops every 10 seconds or so while playing games (anywhere from 5-20FPS out of the blue). I have a 1080Ti, which for these tests I have overclocked to 2050MHz, a i7 7700K @4.8GHz, 32GB of RAM, and a 144Hz 1440p monitor.. For the time being I have only run 2 tests, one in CSGO and one in Rainbow Six Siege, where I have specifically payed close attention to my FPS and tried to get my frames to drop (so that I can try to figure out what is causing it). To be honest, I don't remember what my GPU and CPU usages were before my abnormal frame drops began to occur, so I decided to ask here. Below are screenshots of my GPU and CPU usages in the two games (the first screenshot is CSGO and the second Rainbow Six Siege). Does it look normal? (edit: I do see that my CPU usage in CSGO is really 'wacky' and all over the place, but is this normal, considering CSGO is a pretty undemanding game?)
