I have seen the Pentium D dual core 3Ghz processors. What are some of the benefits of a 2.4Ghz Intel Core 2 Duo Processor over the Pentium D?

Well, the advantages are many. Most notably higher power efficiency (approx. 30W less TDP), and higher IPC leading to much better performance on lower clock frequency. 3GHz Pentium D is easily beaten by even 1.86GHz Core 2 Duo in most tasks. But there were numerous benchmarks on the subject and I am sure you will find the data you need just by visiting few trusted review sites such as tomshardware.com or anandtech.com among the others.
