[Ham-Computers] Seleron Vs Pentium

[Duane Fischer, W8DBF]

Hello All, 	
	
Forgive my spelling of the Seleron CPU, as being blind and having never 'seen'
this word spelled anywhere, I have to guess. 		
	
Besides the obvious lower cost, what are the primary differences between this
processor and the Pentium #4?  	
	
If I opt for a machine using one running at 2.6 GHZ, what am I losing out on?	
	
Thank you.
