Right it seems that the command aticonfig --initial initialized the /etc/X11/xorg.conf file and filled it with the correct configuration for my graphics card. Before I did this the file had almost no information in it so if anyone has a similar problem check that /etc/X11/xorg.conf is set up correctly (might be in a different folder for others). I played UT2004 after doing this and the frame rate issue is gone, even on higher settings. Although the graphics card got hotter there was no emergency shut down and I played it for a while.

If you want a way to check if the file is set up correctly run aticonfig --odgc --odgt --adapter=all (this was suggested in Bill's answer so credit goes to him). This command normally returns performance information about your graphics card. If /etc/X11/xorg.conf isn't set up correctly it will return an error that asks you to run aticonfig --initial.
