So I'm street level computer user with an ATI Radeon 4870 X2 running with Vista64

I'd love to add 4 sticks of RAM and another ATI Radeon 4870 X2, and set up Open CL and have my second GPU running as 1600 cores for some spectacular parallel processing with mind bending multithreading when running Maya 2009, Mudbox, Zbrush or Modo 401 or Houdini 10.

Is Open CL so advanced that it's only in the experimental stage right now, accessible only to a small cadre of C++ programmers, or is there any chance a user like me can tap in on it's amazing potential yet? n

Is there any straightforward installation method where I can just get up and running on it?

Thanks for tolerating a question from the first of the power hungry mobs of ordinary users to come.
