I'm thinking of buying a new Dell PC. They have some great deals right now on the small business pc's.
Anyway, the P4 2.0 cost $290.00 more than the 1.8. Would there be much of a noticeable speed difference between the two?

Also, does anyone know what speeds the P4 will being going up to? I want to get a pc that I can upgrade the cpu a year or two from now.
