KDE 3.01 Install

Hi! I looked a bit on the list but I don't find a clear answer... I want to update my 8.0 running system to KDE 3.01 because I heard that some programs run faster and less bugs. Where can I get the best rpm files to do it (Supplementary/KDE on Suse FTP Site or KDE Site... what's the difference?) and after I have it, how can I install it the best to avoid big problems? Thanks Martin
