If you are planning to buy a new PC than Core™2 Duo is definately the best next generation hardware choice. It is said that performance of Pentium 4 - 3.4 GHZ is equal to 1.8 GHZ Pentium Core™2 Duo Processor.
Pentium D is nothing but 2 Prescott Processors side by side … runs very hot, not a good OverClocker.
Intel Core 2 Duo processors are next gen processors from Intel on 65 nm platform, developed from Ground up with new Architecture called Core, so they are whole new Processors just Jump like Pentium 2 to Pentium 3 or Pentium 4.
Intel Core™2 Duo offers real time multi-tasking performance and will replace all previous Pentium processors.

Lets See What Microsoft says about Core™2 Duo
Maximum everything. Energy-efficient performance. Multimedia power.
Based on revolutionary Intel® Core™ microarchitecture, the breakthrough Intel® Core™2 Duo processor family is designed to provide powerful energy-efficient performance so you can do more at once without slowing down.
With Intel® Core™2 Duo processor, you’ll experience revolutionary performance, unbelievable system responsiveness, and energy-efficiency second to none. And, you won’t have to slow down for virus scan, multiple compute intensive programs, or multimedia downloads, these desktop processors are up to 40 percent faster with improved energy-efficiency.
