I know Celerons are'nt so good i've had one in the past and it was horrible. I figured that with the new Celerons now days it might have gotten better especially in the newer computers like the Dimension 3000. I thought that a Celeron D processor was a better processor than the older Celerons. It is not for me though a friend of mine got it, i did say that the Pentium 4 processors are better but her husband did not want to spend the extra money to get it. So i guess comparing it to a Pentium 4 is out of the question? It won't even be equivalent to a 1.- anything Pentium 4 or anything to that nature.
