expect gnome-shell to need to fall back to a rendering method that'd
be this CPU intensive.
I assume you mean the live installer by this, as the normal anaconda
doesn't run gnome-shell at all. A compositor has some of the same
properties as the X server itself: it _has_ to respond when an app draws
something, otherwise the bits don't show up on the screen. So it's
possible that what you're seeing there is anaconda updating the screen
"often" (more than 60fps, at least), and X and the shell struggling to
keep up.
But this is what profilers are for.

I did a pxeboot install of today's rsync using the anaconda from TC5.
I ran top(1) during the install and did not notice any unusual CPU
utilization.
This is on a 32 GB 3770K.
