T_Bone: Athlons excell in emulations for some reason.
I think it's because AMD uses different low-level timers or something. My Athlon 2600+ is roughly the same speed as my P4 2.4 in benchmarks, but it runs Dungeon Keeper (Win95 version) more than twice as fast as the P4! Also, with the P4, WinUAE is locked at 30FPS with VSync off and will only go full NTSC speed with VSync, but with the Athlon, it always runs at 60 FPS, with or without VSync.
WinUAE and older Windows software really doesn't like the P4 at all.
If I had known my stability problems were due to bad RAM and not the nForce 2 chipset, I wouldn't have replaced it with the P4. Next year, I'm considering an Athlon again. :-)
