Graphics Card's Stream Processors?

I am in the market for a new graphics card. I have a bit limited knowledge of computers, so I need your help to buy the best one. I searched around and found various graphics cards are available in the market to choose from. I also found good discount on graphics cards at http://www.dealrocker.com and http://www.nextag.com. Wondering What do stream processors mean on a graphics card? Can anyone shed some lights on stream processors?

Thanks in advance.

Stream processors are a relatively new technology to be introduced to graphics cards. Essentially, stream processors can be allocated different processes to perform depending on what graphical environment is to be generated. For example, in indoor scenes the stream processors can be set as shaders, while in outdoor scenes the stream processors can be used to map vertices.
Stream processors are commonly used in the newer generations of graphics cards, replacing dedicated vertex shaders and pixel pipelines.
