The Intel Pentium II is easily the best CPU for the average user when considering it’s overall performance. If you can afford the $580 price tag, this CPU will not disappoint. 

This is probably the best CPU in terms of price vs. performance. Its overclocking capacity will easily take you across the 400MHz mark 
for a mere $115.

While it is not a match for the Pentium II’s overall performance, this CPU can match the 3D performance of a Pentium II 400MHz when used with applications that support 3DNow! and is ideal for gamers who are attracted to the $300 price tag and don’t want to try overclocking.
