Unfortunately the latter means that the GTX 400 series (and other first-generation Fermi derivatives) won’t be able to match AMD’s Radeon 5000 series in audio capabilities – NVIDIA can do compressed lossy audio(DD/DTS) and 8 channel uncompressed LPCM, but not lossless compressed audio formats such as DTS-HD and Dolby TrueHD. This leaves the HTPC crown safely in AMD’s hands for now
That's only true for the GTX 480 and GTX470. THe GTX460 can
bitstream lossless audio codecs as can be seen in the following thread:
"With a $199 MSRP and 150W TDP, the 768MB GTX 460 is also the first card to be of a suitable design for HTPC use. Although we don’t expect very many GTX 460s to be used for that (rather it would be for the unannounced GF106) NVIDIA is already putting plans in to motion for HTPC cards. The GTX 460 will offer full bitstreaming audio capabilities, something the GF100 GPU powering the other GTX 400 series cards could not do. This means that the GTX 460 will be able to bitstream DTS Master Audio and Dolby TrueHD along with the 8 channel LPCM audio capabilities supported by the previous GTX 400 series cards. This brings NVIDIA up to par with AMD, who has offered bitstreaming on the entire range of Radeon HD 5000 series cards."
