Fun thing is with a tiny bit of manipulation you can run a P3 tualatin at 1.33ghz via a slot adapter and some pin disablement and some voltage mods (or if you had the right adapter a jumper) in a motherboard which came with a low tier P2 or even earlier. So without replacing your Asus P2B from very early 1998 well up to mid 00s with astonishing performance gains, that motherboard had a massive lifespan in the right hands. Mine is still running with a new voltage regulator to this day.
