To be fair, Kenny, your PC system does sound a bit screwed up, considering I actually had WinXP (Pro) running on a 5 year old K6-II 350 with 128Mb (100MHz FSB) at one point.
It wasn't the fastest set up, but waiting a minute for IE6, well, that's taking the p*ss somewhat. Maybe 5-15 seconds, but a minute?
To strangle an 1.3G Athlon back to slower performance than that old PC sould take some seriously bad hardware or software conflicts.
Win2K sp3 was perfectly usable on the machine (after adding a bit more RAM). Booting took a bit longer than I would have liked though ;-)
