Put it this way
It is no way as fast as the top CPUs today but it will certainly do. That is unles you like playing games on your laptop/pc. Then it could strugle
Yes, but it must be with one of the same type. EG, you can swap an Intel Pentium 3 1.5GHz with a Intel Pentium 3 2GHz, but not with an Intel Pentium 4 2GHz. Also, it must be the same socket type.
Pentium 4 with HT technology runs at the highest speed.
No, in most cases, the Intel Pentium 2.4 outperforms the AMD Sempron 2500+
The Pentium 4 got it's name because it was the next series of Intel's flagship CPU line after the Pentium III.

Socket A.
Pentium 4 vs. Dual CoreThere are MANY differences between these two generations of Intel CPU's. Most notably, Duo Core CPU's possess two processing cores opposed to the Pentium 4's single processing core. While a Duo Core CPU may be operating at a lower overall operating frequency, it is still much more powerful then a Pentium 4 considering it's improved FSB speed, cache size, multiple cores, efficiency, etc.
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.
You can get any graphics card you want, your CPU doesn't matter. What matters is if you have a PCI, PCI-E, or AGP bus to plug the card into.
The Intel P4 is probably fast enough for the average home computer unless they're running an intense application.
