If the CPU can handle it you can try nvidias 3dtv for gaming for free But it stinks for gaming. 1080p is limited to 24fps on hdmi but 720p will allow 60-fps,HDMI just does not have the bandwidth for 1080p at 60 fps only dual link dvi does,possibly Media player classic home cinema,AKA MPCHC will allow hardware acceleration,and hopefully your tv can do side by side or top and bottom 3d playback if you can find the MKVs or just find some stuff on youtube 3D......my panasonic VT30 auto detects the SBS and top/bottom.
Also for bluray playback Arcsoft total theater is 99$ but you can try it for free for 15 days.I tried it and was happy with it but not going to pay 99$ to watch blurays.......VLC player will soon support Bluray they already do but it is a real pita to setup.But i heard they just released version 2.0 for mac that says it will play Blurays but i do not have a mac to test it.
You might as well get a stand alone 3d blu ray player,I rec you get a panasonic since thats the only way you can get the 3d bluray of avatar that is by far the best 3d movie ever.They cost about 120$ and the avatar bluray is avail to you by mailing in a card included in the Box.
My tv came with the physical avatar bluray so i don't know how long it would take to arrive at your house.Panasonic and avatar are linked for some reason.But the difference between 3d avatar and 2d is astonishing...it made me want to sit 3 feet from my 55 inch TV:)For full Immersion
BTW Conan the Barbarian was a crappy movie and to top it off it stinks in 3d well at least the little bit that is in 3d its mostly in 2d though.
