So what are my options?

I currently have a gaming PC which is really quiet, so I'm guessing could easily be used as a very capable HTPC, but how do I get the most out of it? My current setup is a hdmi straight to the TV, and an optical out from the sound card to my amp, which seems to only pass through a stereo signal, even on files with a 5.1 soundtrack. It's pretty lame, and I'm hoping it can do more.
The system is as follows:-
Mobo: Asus P8 Z77 V LE (Has basic audio outs, 3.5mm 7.1 and optical spdif. Also on board HDMI)
CPU: i5-2500K @4.4ghz (Nothing interesting here)
GPU: EVGA GTX 980 SC ACX 2.0 (Presumably capable of 4K and some high def audio?)
Sound Card: Asus Xonar DG (Seems to be great for headphones, but can't seem to pass through 5.1 DD or DTS)
AV Receiver: Onkyo TS XR 605 (7.1, Will decode high def audio but won't pass through 3D to TV)
TV: LG 3D jobbie, probably next to be upgraded.

So ideally what I'd like is a Blu Ray Drive and either rip them to a NAS, or play them directly from the disc. If possible I'd like to use one HDMI directly into the TV, and 1 HDMI to the amp, which would remove the issue of my amp not passing through the 3D to it's HDMI output. Can my GPU even do this? If so, is there some movie software that will get the most out of the system? I don't mind paying if it works. Plus anything else you might think of?

Cheers in advance
John

Cheers for the reply. I actually have a HDMI splitter. I currently use a PS3 to play Blu Ray's, and with the amp not passing through the 3D I thought I could simply split the signal and take one to the TV, and one to the amp. All this did is exactly like you said. It picked up that the TV couldn't handle High Def audio and lowered the output to standard dolby digital. Looks like I'm either going to have to upgrade my amp, or buy a blu ray player which decodes the audio and gives me RCA outputs.
