Noise Ninja v2.13 (~80 % of 4 cores when doing the noise reduction on an image).Nero Suite 7.x (>90 % of 4 cores when encoding).DivX v2.0.0 (47 - 65 % of 4 cores depending on source type, filters, etc.) AutoGK v2.40 (30 - 53 % of 4 cores depending on source type, filters, etc.).


The main thing a multiple core processor buys you is the ability to run different programs at 100% simultaneously. It helps paint the picture of how few programs are multi threaded. Here is an (unfortunately old 2007) list I copied from toms hardware. Customers won't demand multi threading support until the price of software drops below the price of new computers. Their software is already very expensive, so their customers don't mind buying a faster computer every year. There is nothing restricting SpaceClaim or any other CAD software from being programmed this way, but it is currently more complex/expensive to program and there is no immediate incentive for companies to work this direction. Software must be programmed specifically to use multiple cores.
