So I have I have a decent system setup as my media server but I am wondering if my design basis is all "wrong" for my need. I have 3, 4k "smart TVs" in the house 1 ROKU, and 2 using Google TV through Samsung. All 3 of these require my stored content to be transcoded because of the audio. (I have full audio in my files where as the TVs cannot handle that natively) My server is an AMD 5600x, w/ 32mb ram, and a GTX 1070 (this also serves as a gaming system for one of my kids) The server has all of storage and RAID setup in a full tower. The problem I am having is I can transcode 2, 4k streams at most, and my kid cannot play a video game while streaming/transcoding any 4k video. Do I just need to put Nvidia Shield TVs on all of the TVs and move away from server transcoding all together? The 1070 is getting "long" in the tooth and I have another kid that will soon want to play PC games with us, so I need to start planning my next "budget build" If I updated this system to a 3070 or something along those lines, would I be able to transcode 1 stream while they are playing? My goal here is to maximize functionality with minimal cost. Getting 2 more Nvidia Shield TVs is about the same price as a used 3080, so in theory if I can just upgrade the GPU to meet my needs I can save a little money and start the next budget gaming build for my household.

I would give the wireless a try and see if that works a little better. If you only need to transcode audio for playback that is a very light operation that should not affecting their gaming. I know that wifi can still be hit or miss, for whatever reason the 5 Ghz on my LG C8 basically doesn't work at all and I have to use 2.4 instead, but that's fine for me because I just use a Shield anyway (which does have a 1 gig port on it, but I'm still using wifi).
