Re: getting a new CPU - is it worth?
I just did exactly what you are trying to do. I would say it did make an improvement over my old processor but for the cost it was not worth it. I was very unhappy with the results and I ended up selling my whole system and buying a new one. I actually upgraded to a high end PC but only because I got $500 of unexpected money. But to get an AM2 platform with a 4200+ dual core was very cheap (like $200-$250) for RAM/Mobo/CPU and then use all your old components. If you do this as well you can upgrade alot easier to a 6400+ dual core for like $150 when you get the money.
