Set this all up last night.
Used the Mrs' laptop as the streaming device hooked up to the lounge TV which is also running the Philips Hue lightstrips and ScreenBloom
for an adhock Amberlight setup.
Streaming worked well over wifi for both computers, I was surprised. A few micro pauses and the occasional image degradation for a few seconds but Skyrim was playable. A few of my non Steam games were a bit of a pain to get working like Battlefield and GTA so its not a perfect solution by no means but it worked well enough for a wifi performance test.
The ScreenBloom software worked very well in conjunction with analysing the screen picture and adjusting the average colour of the Hue lightstrip to suit.
I think for serious gaming ide either pluck the PC box and place it alongside the entertainment cabinet. My Sim racing rig isnt the most comfortable place to spend a few hours playing an adventure or FPS game, even with the luxury of triple screens, the whole rig is built to be a sim racing unit first, desktopish setup second so a lounge room option is handy.
Im contemplating a PS4 but not sure yet. Being able to play games like Red Dead Redemption 2 when it comes out is a major factor but im willing to wait on that and give the PC box a go in the lounge room hooked up to the Hue lights first, just dont want to have to move it all the time...
Keeping a close eye on the Philips Hue Entertainment update which is slated for early 2018. That might drive the PS4 option a little harder and the kids will love it and itll require far less configuration.https://developers.meethue.com/entertainment-blog
