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.. > >> 3) The 2 lowest-priced Nvidia's at the local store are... >> >> Asus EN210 SILENT/DI/512MD3/V2(LP) NVIDIA GeForce 210 Chipset (589Mhz) >> 512MB (1333Mhz) GDDR3 DVI/VGA/HDMI PCI-Express 2.0 Graphics Card >> >> >> and EVGA GeForce 8400GS 1GB (01G-P3-1302-LR) nVidia GeForce 8400GS >> Chipset (520Mhz) 1GB (520Mhz) DDR3 Dual Display DVI/HDMI/VGA PCI Express >> 2.0 Graphics Card >> >> =C2=A0 Any preferences? >> > > 1GB of GPU RAM looks like overkill if you just want to watch videos.

Honestly, this is the card I'd recommend if you're not doing any heavy gami= ng. http://www.newegg.com/Product/Product.aspx?Item=3DN82E16814125402 It's cheap, dead quiet and has full hardware decode of h.264. --=20 :wq
