Well I believe that the FX-57 is the top single core and the X2 4800+ is better than the Pentium Extreme Edition in cirtian apps and definitaly in gaming.
We are not talking about whether the 4800 pwns either way, we are talking about single core processors. Dude, I dont know where you guys get it where you think that just AMD "Pwns". Read a book about it someday.
