My major question is, is there anything concerning about being over 50% constantly?
No-but you will want to look at your hard drive activity which will likely be your bottleneck. If your filesystem become fragmented or you have too much IO and the system crawls to a snails pace then you will see substantial degradation in performance of AV content playback/recording.
Antivirus programs are notorious for being resource hogs and hook the filesystem and networking protocols so that they can inspect every bit coming/going on the machine and scan/quarantine it if necessary.
Most things are IO bound nowadays, not memory/CPU limited.
