Intel Core Duo processor worth it ?

The problem with dual core processors is that not all programs are multithreaded, which means that they can be broken down in to multiple processes. Most video and photo editing software are, buy very few games are. On a multithreaded program you can expect an 80% gain in processing power from you dual core. So really it depends on what you are going to use you lap top for. On a non-multithreaded app, you will still receive some gain, because background tasks are given to the second core. Personally I would go with the duo, just because more and more programs are becoming multi threaded.

It is true that the AMD counterparts outperform the Pentium D processors. But to answer your question...you need to take into consideration what type of applications you are going to be running. For example, I edit video for a living. The computers I use for that are equipped with Dual Core Processors. But my gaming computers are not. As for your two choices, I would pick the Toshiba becuase I think they make a better system than HP does. Additionally, don't pick solely on the processor. Memory, expandability, graphics, connectivity, and hard drive space are important too.

I agree with afore person. But if your going to get a dual core it should at least be 2.0ghz and be an AMD because they are 64 bit processors and will be compatible with the upcoming era of 64 bit applications. I.E. you wont have to buy a new computer when 64 bit apps take over.

well think about it, two processors so the load on each one is cut in half

so that means they run a lot cooler

and with the load being reduced the life of the processor will increase a lot
