When Ageia released a PhysX physics processing unit several years ago, many people thought the technology would never catch on; simply because it was another thing they had to buy, another add-on card. However, while they were right in that the PPU itself didn't do so well, the technology did and has now been encorporated into nVidia's GPUs.Today we're looking at a product with a similar pedigree in that it doesn't have everyone convinced.

While we don't know whether this will ultimately end up as another onboard GPU chip, let's see if it's worth your money in its current form.
