It wouldn't make much sense to do so.  The speed-up will in fact be
minimal.  Moving uncompressed video from a the GPU to system RAM isn't

Video encoders that run entirely on video-card GPUs are more promising,
but offer terrible quality and little speed improvement right now.

Personally, I'm pretty content to see more and more use of SIMD
instructions on modern CPUs in optimizing multimedia playback/encoding.

Don't trust me! I'm wrong!
