I have PS3 Media Center installed on my server with 4GB of ram and I believe an older ~2Ghz Core 2 Duo processor. Anyway I currently have no GPU installed, just the onboard Intel graphics. If I get a cheap card like an nVidia 8600GT would take offload some of the transcoding from the CPU onto the GPU? My work around for this has been just running PS3 Media Center on my main computer (i7 920 @ 4Ghz, Radeon 6970) and having it access the files on my server. The videos play fine off the server with PS3 Media Center but I think it might struggle with the higher bitrate 1080p files, also, I don't want the CPU usage to be so high because it slows down file transfers for other computers accessing the server.
Is what I'm asking for possible without a plug-in, if there is a plug in to use what is it?
