The E-350 doesn't support 3D matey, it has no HDMI 1.4 capability.
The E-450 does however.
What board do you have?
HTPC enthusiasts also get AMD's latest UVD 3 technology, with support for HDMI 1.4a that provides enough bandwidth for everything up to Blu-ray 3D

The 6310 definately has enough grunt for the job. But you will have to see whether your TV/monitor will work with the AMD chip.
Unfortunately, the fact that the 6310 gpu in AMD's E-350 doesn't support MVC acceleration means the two processing cores would be tasked with trying to handle Blu-ray 3D playback in software (ultimately, they're too slow for this).
The E-450's updated 6320 gpu does support MVC acceleration.
So would seperate GPU take care of that fine then? (like a GT520 or ATi 6450)
