People like you can use a faster chip...
But consider how most computers are used... I have a GHz processor on this laptop I am using... so far I have used it to write, use the internet, and play games- the only thing that comes close to using that speed is the game...
I am not being snobby, but most people really dont need a 3 GHz processor- hell, I dont need a 1 GHz processor for 99% of the things I do on my computer...
I am NOT saying faster processors are silly- The faster we can make them the better... All I am saying is most people wont really be able to tell the difference between 3 GHz and 30 GHz...
