Tobes you have absolutely no idea what you're talking about when it comes to overclocking, I'm not flaming I'm just saying you are going to make a fool of yourself.
Asides from the massive change in architexture that has happend from a p1/k6 to a p4/opteron/athlon, and the fact that there dual core, you cant overclock a p1 to be as fast as a p4 it just doesnt make any sense. So before you go and post something where YOU just look like the raging fanboy, do some research.
As for XFX I've heard multiple bad things about them in the past, but apparently they are improving. Screw it though when EVGA is awesome, and are very nice about tech support. To me EVGA and BFG are the only ones I'd buy unless there is a compelling reason to go with another make.
Maxtor is Fine IMO, I use it as my storage drive, it was nice and cheap. I like my raptors more though
