    Not quite. It's a physics processing unit (PPU). It is a card that compliments a graphics card. It has a very specific task: To calculate the physics of a game. The graphics card then renders the results.

    Example: In a first person shooter you hold a gun up to a zombies head and pull the trigger. The result is a million pieces of zombie brain go flying. The physics card will figure out which direction each piece of brain will go and how fast each bit will go, given the weight & trajectory of the bullet and how close you were when you pulled the trigger. The graphics card will then render the results as as on screen graphic representation.

    Without the physics card the physics would be left up to the CPU, which would slow the whole thing down.

    Some people think PPU's may just be a passing fad as multi core CPU's can basically do the same thing by devoting one thread to physics.

    If you have to ask, chances are you do not have one, as they are a somewhat specialist item used in high end gaming systems. You dont need one unless you are seriously into gaming, and even then it's doubtfull.

    Thanks. I'm sure I haven't got one and with a dual core machine and not a big gamer, it doesn't look like I need one or tat it's the cause of my issues in my other thread
