Question about CUDA!

Greetings,

I recently discovered the GPGPU technique and the CUDA architecture. Plus I found this CUDA driver for the Mac: [url=“Apple - Support - Downloads”]Apple - Support - Downloads

But I’m not sure how this technology works!

In addition to the graphics card my monitor uses. Do I have to add a second graphics card for the CUDA processing flow? Does all my applications and programs, for example Final Cut Pro, utilize the GPGPU technique once the CUDA driver installed?

Thank you,
Amin,
