I had a 486 dx4/100 there was a checkbox in winamp options you needed to tick in order to be able to play mp3's, I've long since forgotten what it was labelled but when you checked the tickbox it worked and audio played correctly but basically pegged the entire cpu - forget about skipping or being able to seek within the track. Just moving mouse cursor etc. was massively delayed the whole computer was unusable until the track finished playing. My next computer after the dx4 was a Pentium 166 MHZ - it could play mp3's and Quake simultaneously.
