I was thinking of real CPU usage numbers like from e.g. task manager or similar tools.
MPlayer only shows time used, that can be far of from CPU used.
Either way this looks fairly consistent with vsync issues.
Also your issue is almost certainly the colorkey. Keep in mind that colorkey is a per-file option, so make sure to specify it before the filenames.

I had intentionally asked for videos to be created at 30 or 60 fps because I thought this would match up better to the 60 hz refresh.  What would you suggest for a better playback at 60 hz?  Would 59.94 fps work better, or is that still too close to the refresh rate?

That would probably be worse. Using Aero/a compositing window manager and disabling vsync in MPlayer itself should be the easiest solution.
