PPU Processors?

[StealthyFish]

wow, well, while I was screwing around at Alienware's site to see the most expensive computer I could build (my friend hit 52k USD with a dell server =O ), I came across a Physics card. What exactly is it and what does it do? Does it lessen the processes on your processor when you do have to calculate physics and things?
