I remember being jealous of my friend's Pentium (66? 90?) when mp3 playback slaughtered my 486.
Was on par with a 90 Mhz Pentium for integer processing, IIRC, so MP3 playback didn't drag the system to a halt, though it was still a noticeable impact on performance.
What really dragged the performance down was when I'd try to run 3D Studio MAX at the same time. I had 24 MB of RAM, and the installer warned that they did not recommend running with less than 48 MB, which was an absurd number for a home user at the time.
Now is actually a decent time for a naming scheme change, right? Apparently Golden Cove is supposed to be a bit of a jump.
