The consensus seems to be that a Pentium 3 is 15 and 35 percent faster than a Pentium 4 clocked at the same speed. I'm in an early state with my purchase decision, so I have room for changing my mind. I'm still saving my pennies, at the same time watching the market for new developments. Usually I buy a new PC once every three years, and I buy a processor which is about 6 months old in order to get a good compromise between price and performance. I'm a bit nervous about getting an AMD processor because of all the heat-related problems that I had the last time I bought an AMD processor in 1998. (Sorry, I can't remember the specs). I exchanged the processor (and the whole motherboard) after a few months because it crashed every time I ran a Fritz analysis overnight. Have AMD really got their act together with the heat problems?
