No, not true. It used to be that way, but things are changing. There are programs, mostly any decent encoding software, that has had multi-core support for some time already. Other programs are getting there, like the latest WinRAR and Office 2007. Then there is the whole gaming side of the coin. 2007 will be the year of the multi-core revolution in gaming. The Doom 3 Engine already has dual-core support. Valve is updating the Source engine to support multi-core. Unreal Engine 3.0 has multi-core support. Most games coming out from here on will support multi-core, and there are even some (Alan Wake) that require dual-cores. DirectX 10 makes use of multi-core.
I haven't even touched upon the other use of dual-cores: multitasking, which is running several programs at once. If you've had a look in the task manager lately, you'll know you are doing it. The most noteworthy situation is when you are running two CPU intensive programs at once. Like using VoIP while playing a multi-player game, or just playing MP3's instead of the games own music. Doing other thing while running virus or other malware scans. Checking email, surfing, working with a couple office applications, and having all your security software running in the background.
When upgrading from my socket A system a couple of years ago I was wondering if dual-core was the right way to go. I am an multitasking fanatic but I could get a faster single-core for gaming instead. The dual-core was the right choice. The only reason I notice the anti-virus is scanning is because programs take longer to load, thanks to the hard-drive being a bottle neck.
I maybe should add that to multitask you need a lot of memory as well.
Oh, and then there is the thing that nowadays you can't get a fast single-core anymore. All mid- to high-end processors are dual-core (except the quad-core).
