I suggest that you use an AMD 75-133MHZ if your board voltage supports its
requirement of 3.45 volts. You can get P100 like performace by o/clocking
to 160Mhz - but some board will only allow you to run at 120Mhz which is
still better than the Intel. Remember to check your mainboard manual that
it at least supports the AMD DX2 chip (or AMD DX4) because the system has
to recognise it as a AMD - not a cyrix or similar.
