I use a p4. Sometimes, when I am listening to music and have opera, internet explorer, outlook, agent, foobar open at the same time, the music slows down or gets a glitch when I open up a folder or change programs. Or when I run a spybot scan, it hogs most of the cpu resources and switching to a different program or opening a folder takes forever. Do these admittedly rather minor annoyances go away with a dual core cpu?
