Re: What card for 1080P60 with XvMC
XvMC works very well. The hardware decoder on my GT6600 is nicer than software by a fair bit. Try a HD video to see what is possible.
You need either xine with xvmc, a recent library would help or mplayer built with --enable-vxmc --with-xvmclib=XvMCNVIDIA and run with -vo xvmc -vc ffmpeg12mc.
