AGP 4X ?? What the heck? Thats ridiculous, I set mine manual for faster times. I found that my kt6v-lsr was the most stable and tough enough not to freeze when bogged down, but I sold it when I got my asus. It works but I dont see no drastic improvements. On XP the nforce chipset sucked real bad when moving files, on 98se its ok. I'm not sure what happened but socket a got ditched and people were left hanging if you ask me.
