I try to stream 4K on YouTube and my video player and in both instances they seem to require the use of the CPU instead of the video card.
Do I need 2 video cards to play 4K videos?
No. you need a Fast CPU and Fast Internet.
Apparently my 8350 is not fast enough. I only have about 50 something megabytes of Internet speed.
Correction:I think my 8350 processor is not fast enough.
Sorry Kat,I apologize for putting the word "apparently" did not mean to offend anybody.
Do you even have a 4k monitor/tv to stream to since most modern ARM CPUs can playback 4k. Run a speed test on your internet to see what your real speeds are and also you may be being throttled so a VPN may be required.
I currently don't have a 4K monitor only a 1080p monitor.
The results of my Internet speed tests are only 30 MB per second.
I went to see if I could run 4k
you are wrong, its not 30MB per second.
Well the minimum is 20Mbs when audio is factored in
Most current smart phones could play back 4k
Also it mights be the scaling that is killing you.
Less compressed 1080p will look better on a 1080p display than the highly compressed 4k that Netflix uses.
Oh 4k doesn't work on PCs anyway

I don't understand why would you say that.
there is a very big diffrence between MB/s and Mb/s
lol
how do you see 4k on 1080p monitor .. 
damm that upload spead sucks, only 840KB/s.
No wonder even streaming to youtube at 720p would suck with that upload speed.
Are you realy sure, you understand everything?
Netflix and Amazon are blocking 4k on the PC anyway......
Cox communications have a download speed, but the upload speed sucks. Normally it's supposed to be 59 Mbps but sometimes it's just that speed in the picture.
yeah but streaming depends on your upload, not download.
And your upload is only 840KB/s in that test.
The Amazon video quality sucks anyway. Not worrying about that.
Sorry Kat
i duno, looks pretty good on my fire-stick
In Australia we get 5 mps and a upload of .50
