I just bought a KT333/Ultra Dragon Platinum Edition and an Athlon XP 1900+. I use a retail fan and it runs at about 40-45 degrees. Should I overclock it at all? And should I raise the FSB? What should be changed (from the default settings). I noticed my CPU is the bottleneck for my 3dmarks score so I want to overclock it if I can. Thanks for your help.
