i was looking on newegg and i found two pentiums that were arond the same price, which one should i get. Intel Core 2 Duo E6300 Conroe 1.86GHz 2M sharing L2 Cache LGA 775 Processor or Intel Pentium D 945 Presler 3.4GHz 2 x 2MB L2 Cache LGA 775 Processor. looking at the Operating Frequency 1.86GHz to 3.4GHz seems like an easy chose but then the FSB 1066MHz to 800MHz the tides turn. my question is which is better and how come.

The Core 2 Duo is the replacement for the Pentium D so when stock is exhaused, Core 2 Duo will be the way forward at this moment in time. Until the next processor comes along.

Anyway, compared to Core 2 Duo, Pentium D is the cheaper and slower solution.

One of the biggest mistakes people make nowadays is judging a processor by its clock speed/operating frequency/whatever you want to call it. The days of the gigahertz wars are long gone simply because of one reason: how the structure of the chip is built.

In theory, a higher clock speed is "better", but you aren't looking at the fact of what can be achieved in each cycle. If you ever compared AMD processors versus the old Intel Pentium line, you'd noticed AMD always had considerably lower speeds. However, the chips were able to do a lot more with each cycle because of its architecture and thus a 2.13ghz AMD chip would be equivalent to say, a 2.8ghz Pentium.

The Core 2 Duo chip is by far the better buy. Don't be deceived by a higher ghz rating, it is absolutely meaningless this day in age. The fact of the matter is, ghz ratings mean different things for different cpu's. There is no general guideline anymore.

As well as what Secret Master has said, the new processors being released today are mainly dual core processors, meaning the chip has effectively two processors in it. This is what the Core 2 Duo is, the Duo means dual core. The P4 you are looking at is a HT, virtual Dual core and in benchmarks despite the Core 2 Duo's lower clock they are the best processors around at the moment.

The only chips out today are some new ones for the AMD 4x4 platform intel havent released anything since the core2s came out.
