Question / Help CUDA or OpenCL encoding on an additional graphics card?

Forgive me if this is a redundant question, but I have done a search and I haven't seen a post with my specific question so I figured I'd ask myself.

First, my streaming setup. I'm aware it's not the latest and greatest hardware, but it's what I have.

CPU: Phenom II X4 965 @ 3.4Ghz
GPU: Nvidia GTX 470
Additional GPU: 9800 GTX+

I know encoding on these older graphics cards is possible with CUDA and/or OpenCL.

What I would like to be able to do is offload my video encoding to my second GPU which sits completely idle 99% or my gaming time. Most of the talk these days is the ability of the GTX600 series and newer to encode with their dedicated silicon. I obviously don't have that luxury.

Even if it's horribly inefficient and broken, I'm curious is a plugin exists that would let me do my encoding on the 9800+.

Thanks for your time.

Not possible, sorry. x264 supports using OpenCL to handle rc-lookahead work but that's about it.

OpenCL and CUDA are not designed for the kind of complex processing tasks that are involved in video encoding, anyway.
