Why do people bash Opterons so much? They aren't bad CPU's at all, and in fact, they are more similar to the Athlons than you think. I found this quote on another forum.
"Opterons are the cores that past the most stringent of testing, because they are meant for servers/workstations and 24/7/365 use without failing. (This is also why they overclock so well.) The ones that fail, but still past stringent testing become the X2 4800s and FXs. The rest become regulars A64s/X2s."
Basically, Athlons are made from Opterons, so its not like Opterons suck and Athlons rock, they are the same processor, its just the Opterons are more stable.
