Task manager substitution (SuSE 8.2)

Hello In order to help recent converts from microsoft, I've been looking into a graphical program to allow process monitoring and manipulation. Does anyone know of a "pretty good" program with GUI that would allow one to monitor performance and effect kill commands to running processes? I downloaded gPS from tucows and I'm in the middle of compile-hell. Should I continue down this path or is there something else out there? TIA & cheers <rant> Why would gtk-devel not be part of gtk sources? Who in their right mind go through all the trouble to compile gtk libraries unless they were "developers" also?
