I take it then than this is normal and no need for concern.

Yep, playing certain high end games and video rendering are two of the
most demanding things you can ask any computer to do, even a high end
one because so many pixels are getting moved around. With video games
you obviously see a lot of movement and rapid changes on your monitor.
With rendering you often are changing many thousands of pixels in each
frame and at 30 frames a seconds things get kind of busy meaning both
a lot of disk activity and calculations within the CPU registers which
is memory intensive. ;-)
