I'm not aware of any video decoders using CUDA, OpenCL, or pixel
shaders for video decoding; AFAIK, unless you're using VDPAU you're
still using the CPU to render the video to a frame buffer. The most a
video player is going to use OpenGL for is stretching that frame
buffer to fit a window or screen, and possibly as a compositor to
place overlays like subtitles or playback control elements..

Yeah, RAM isn't going to be the issue here.

Honestly, this is the card I'd recommend if you're not doing any heavy gaming.

It's cheap, dead quiet and has full hardware decode of h.264.
