If it's just a P4 and not at least a Core 2 duo... realistically, maybe $25 (and that's for the whole computer, not just the CPU). Used computers really aren't worth much.
Not much bigger than the chips of today.
The Intel Pentium Dual-Core is much faster.
The "max operating temperature" of the original Pentium is 85°C. While it could theoretically run hotter than this, if it got much hotter, it would malfunction, and likely destroy both itself and the motherboard.
There were a few laptops that used Pentium 4s. However, Pentium 4s generated too much heat and drew too much power for them to be practical.
The first Pentium Is required a voltage of 5 volts.
As a whole, the Pentium 4 has a higher maximum performance than a Pentium III. The Pentium III performs the same as or better than Pentium 4 at the same clock speed, but the Pentium 4 has a higher max clock speed (which the Pentium 4 was designed for).
No. It is much more powerful.
it is 35% faster than Pentium
The Pentium D is not much faster than a standard Pentium 4,and it uses more power. Dual core processors are the fastest available at this time.
The Pentium 166mhz is a old socket 7 a very early Pentium prossessor,The Pentium 4 is modern form factor,much faster and more prossessor cach than the old chips.

This is dependent on the type of code being run, as well as the clock speed of the processors. 16-bit code, for instance, was much slower on the Pentium Pro than the Pentium, while 32-bit operations were generally slightly faster.
