I have almost the same mb (M3N78-VM with nVidia 8200) and propcessor,  
but only running with 1G ram. I have had no problems with playback of  
HD content on 1080. I would first make sure you have the Nvidia  
drivers installed from their website. Also another thing that helped  
me in the past was to stream from the backend, not from a smb or nfs  
mounted share. I have tried other settings off and on and nothing  
really caused any problems. Make sure you have 256MB video buffer  
enabled in the bios. I currently use CPU++. I had a problem in the  
past with a different mb where the cpu would throttle back because of  
heat and would cause stutter.
