From the article found here.Folding@home is a distributed computing project designed to perform simulations of protein folding and other molecular dynamics, and to improve the methods of doing so. Also referred to as FAH or F@h, it primarily attempts to determine how proteins reach their final structure, which is of significant academic interest and has major implications for research into Alzheimer's disease, Huntington's disease, cancer, and many other afflictions. To a lesser degree, Folding@home also tries to predict that final structure and determine how other molecules may interact with it, which has applications in drug design
Where to get the folding client
Go to the Folding@Home website and download the appropriate client for your machine.
For Windows Simply click the "Windows All versions" link. For Macs, or linux Computers click on "Other platforms" and select the client best for your system. The PS3 client can be found at the bottom of this list. And older GPU and SMP clients can be found here.
Differences in Types of Clients
There are basically 3 different of PC clients, CPU, SMP, and GPU, as well as a PS3 client. With version 7 the client will offer you modes that will work for your PC.
CPU clients will use a single CPU or core to fold with.
SMP clients will uses multiple CPUs or cores to fold on.
And the GPU clients use the graphics card to fold on. The GPU clients using Nvidia cards will use a small percentage of a CPU or core, where as an AMD card will use up a whole CPU or core.

Is a passkey important?
A passkey is only required to receive bonus points. Currently all WUs that offer bonus points are tied to the SMP client(most of which are the bigadv WUs). To get a passkey click here and fill out the info. You need to have completed at least one WU in order to get a passkey.
