I didn't make myself clear.  Sorry
I agree with you .. my point as below is that earlier distributions provided 
applications that weren't as capable, thus demanded less from the host 
system.
A full GUI install of RH9 imposes less of a load on the CPU than a similar 
Fedora installation will, assuming the user makes use of the new generation 
Fedora GUI apps on the Fedora installation, but uses RH9 generation apps on 
that installation.
