It's just a P3 coppermine, but they can make a nice upgrade on an old BX board. I have one running in an old Dell XPS R400, formally running a pentium 2 400. FSB is not overclockable, these types of computers and other BX boards can make good use of this cpu.
Unfortuneately, looking at pricewatch reveals that this might not be a hot deal, but an average price.
