To Archive and Install, or Not

[John]

I have an installation of Jaguar archive and installed on top of 10.1, 
and am a bit unsure what to do with 10.3. I bought a faster larger 
drive, which is very very nice (carbon copy cloned), but am not too 
sure if I should back all of my data off my internal drive, and wipe 
the internal. This means somehow I have to get all of my settings onto 
the new installation of Panther (mail, safari, network settings, 
etc.......).

So, will I get better performance if I do a clean install?

Thanks!

John
