Right. Everything you said is very interesting. I bought a computer 3 year ago with a slow processor ( AMD Sempron 3000 ), I don't know much about computer at that time and I bought it because it's the cheapest. After one year, the computer ran very slowly, although I only searched the internet, checked mails, downloaded picstures and never played games. I upgraded a lot (RAM, hard drive...) with lot of money, but it didn't get better. I'm tired of it, and was forced to buy a new one with Intel Core 2 Duo processor ( the newest processor at that time) , and the price is three times more than the old one, and now over one year it still run very fast and I don't need to upgrade anything. The quad-core processor is coming now, if anyone has a chance to use it, he will learn the difference between Celeron and Quad-core processor.In conlusion, in my opinion, spend more money to buy a better computer with better processor. Otherwise, someone will regret because he spent a lot of money to upgrade and it won't last better.
