Hi all,
looking for some advice on what to do; currently our HTPC is running an AMD E-450 Fusion, it's working fine although I find it to be fairly high on CPU usage overall (mostly running as torrent server and network share) and the main issue: I cannot get it to properly play blu-ray 3D

Using either PowerDVD or TotalMedia Theatre 5 doesn't matter, CPU load is up and around 100% all the time whilst GPU is more or less idling, so I guess it's a software issue or the E-450 GPU simply cannot handle the decoding?
I want to amend this problem as I simply want one system to run everything (as an alternative I've tested running the 3D stuff from my laptop, which worked fine for the most part with the exception of some laggy scenes).
1) Somehow find a solution for the E-450 to manage blu-ray 3D?
2) Add a GT520 or something of the likes and see if that solves the 3D problems whilst keeping power consumption low?
3) Replace the E-450 setup with either AMD X4/X6 or Intel i3 of some sorts?
For info I'm running HDMI from the HTPC to amp and from there to 3D pj, so it's "real" 3D I'm after (stereoscopic I believe is the correct term). The current setup is using around 50W "idle" (running uTorrent, not much more). I'm placing that in parenthesis as CPU usage is around 30-40% all the time regardless.... Thought it'd be lower but I guess it's the PSU and HD's and all.
My main priorities are low power consumption as it's more or less running 24/7, and then I want it to simply manage whatever movies we throw at it. It's not used for any gaming or such, so no requirements there whatsoever.
I'm more or less lost at the moment, so would be very thankful for suggestions!
