Radeon 5570 and GeForce boards on same machine

Radeon 5570 and GeForce on same machine

I recently purchased a Radeon 5570 (for reasonably priced programatic

access to DX11 APIs on Win7-64). I am also interested in programming

parallel computing routines with CUDA on a low-end NVIDIa card. I am

indifferent as to which card drives my ancient LCD monitor.

Is it possible or even wise to install both cards on the same machine

with the understanding that only one would be used to drive the

monitor but both would be available for programatic use of their APIs

and for executing programs developed using these APIs.

I look forward to all of your advice, experience, and horror stories.

Thanks in advance.
