its not about the Ghz, by the way, you do know that the number+ (e.g. 4200+), gives its pentium equivalent I believe. So your 3800+ would need a pentium 3.8Ghz to even come close, and then some to be honest.
That is why AMD's are efficient, and popular in a place like this, where people know what is going on!!!
Need any more advice just ask!
