I already have a music system set up with a Marantz cd 5004 Schiit Asgard 2 and The Sennheiser hd 650, but what do I need to purchase to experience hq sound for my tv ONLY using my headphones. I live in the house with other people and want to keep the noise to myself. I was thinking a receiver but I don't know what that does or how to hook it up. Do I need to hook up something to my tv or game system. I'm clueless sorry.

A modern A/V receiver would help.
Connect all your sources (using HDMI), Cable TV, Blu-ray player and gaming consoles to the receiver, connect receiver to the TV (HDMI), plug headphones  (HD650) directly into receiver.
Some Marantz receivers come with Dolby Headphone, most Yamaha receivers come with Silent cinema, Yamaha's own headphone surround sound technology.

Does the quality of the receiver matter?  How does it effect the sound? Any recommendations?

Why can't you connect the audio out of the tv to your headphone amp? If for some reason you don't want to use the your headphone amp for that, you could get an inexpensive headphone amp to use just for watching tv. 
 
Some televisions even have a headphone jack, although it won't be as good as your headphone amp, and might not have enough power to properly drive the HD650.

I didn't know I could do that. What do I do if I have a digital out on my tv but not at digital in for my amp.

The more the receiver cost, chances are it sounds better.
 
The Yamaha RX-A710 is almost the same as my RX-V671 (RX-A710 slightly newer revision).
The RX-A710 uses better speaker amplifiers, then the next cheaper model.

So use the line out on the tv.

If your TV comes with an optical output port, you can get something like the Schiit Modi optical DAC.
You could run an optical cable from your TV to the Modi (optical) DAC, the run an analog audio (RCA to RCA) cable from the Modi to the Asgard.
But you would not get headphone surround sound with this type of connection, just basic stereo audio, it would be really good sounding stereo audio.
 
What is the make and model of your TV?
Which gaming system is it?

Its an LG 2013 and I have a ps3

so will you use it when watching tv only (cable?) or when playing ps3?

providing the specific model of your LG TV will certainly help
