wtf? why do ppl have to announce "I am an AMD man" it's like going into a biker bar with a suit and tie and yelling "hey, relax bro's, I'm a biker too!" (sh!t, this ain't the amdzone or is it?)
on to your Q. yes by all means use ASII on the pee3, it will run alot more cooler and your friend will be a happy blue man.
"Amd cpu...Gone in 2 secs flat, it truly is a fast chip!"
