What hardware is really necessary for steam in home streaming?

Ok so this is mostly just me being intrigued and (probably) moronical but if you know the answer please let me know. I just entered the world of PC gaming this last week and I'm really enjoying playing games that look and feel much nicer to play than before and I quite like tinkering around. For instance I made steam boot up in big picture mode when I turn on my controller and press start and I decided to check out steam's in home streaming with my surface pro and it runs better than I initially expected which made me ponder what kind of hardware would one really need for in home streaming? I honestly have no clue and if someone could point me in the right direction that would be great. It would be great if I could stream downstairs to the TV on a NUC but i'm not sure if we're really there yet.

 

Anyway if anyone knows that would be great. What experiences has everyone had with steam's in home streaming?

I have used it with a gtx 670, 560 and a 860m and a 750m on OSX, Linux and Windows 7 & 8.1  it seems to work well across the board. Your router is the most important thing for smooth game play.

I think they are on to something. Now if they can get this to stream to ARM devices other than the shield. Imagine stream to a chromecast, roku, phone or tablet would be so cool. The future of Computing is personal servers with small thin clients. 

Well I've streamed 1080p over my laptop on the middle stream setting and I was getting about 30fps.

The laptop has a 1.8Ghz dual core i3 with 4 threads and intel HD4400 graphics.

It only uses about 30Mbps of local bandwidth to play 1080p at highest stream settings.

I use it on a Dell Venue 8 Pro tablet with an Quad-Core Atom and it works fine for me as well. and the clock-speed on it is 1.8ghz. it's pretty good it does come down to your internet speed though

I will say this you will feel like a god playing PC games in the Lavatory.

Specifically, each machine needs a GPU capable of real-time video encoding/decoding (which is almost any GPU). You also want a decent network setup. Far as I can tell, that's all there is to it.

I think my problem is probably my internet connection at home. How much difference can a different router actually make?

Your internet connection doesn't matter. Steam In Home Streaming is just that- in home. The traffic never leaves your network. 

A router can make a pretty big difference. A high quality wireless N router is recommended and you don't want to be too far away from it. (Good signal strength)

The actual device receiving the stream doesn't need to be powerful at all.  

Could you point me towards said routers? Or what to look for in a router?
