I'm pretty confused about how your endpoints are connected to your server; are the TVs functioning as monitors for the server? Or are you streaming via the network? Maybe it would help to draw a connection/network diagram?
In the streaming case, the video cards are irrelevant (as noted above), it's just a function of CPU usage for transcoding (if necessary) and network usage for transmission.
If you're directly connected via HDMi than it's baffling that you're having problems. The video output in MC for linux is more like red october standard than red october HQ, it can happily run on even very low-end systems. For example I use MC for linux for video on an intel compute stick with integrated graphics, and have no issues with buffering or frame drops at 1080p. My guess is that you almost certainly have an issue with your linux graphics configuration (or possibly your older video cards aren't well supported by the nvidia drivers anymore, they do drop support eventually).
It's hard to know because you're using kind of old components in your new system; I'm not sure what the minimum specs are for MC for Linux video. Your CPU launched 7 years ago, and the video cards are nearly 10 years old. Graphics cards in particular have come a long way in the last ten years. For example, I think based on benchmarks, the integrated graphics on a modern high end intel CPU will outperform one or both your video cards, and a single two-year-old midpriced nvidia card would outperform both your video cards almost three-to-one:

Your response needs replying to immediately.
My cpu is intel 990 X with 3.47 ghz SSE x 12, meaning 12 treads.
The GPU is the GTX 9800 GX2 with 2048 meg of memory. I have 2 on this new PC in SLI mode.
The current driver is 340.102 released by Nvidia February 2017. The first driver that was detected at 1st boot, first time was the Nvidia driver. I checked the Nvidia site to make sure the driver is current and appropriate.
All Nvidia cards have new drivers, I was surprise to find out Nvidia has updated the drivers on their cards so that they can play most new games.
Did I forget to state that the motherboard is Gigabyte G1 Assassins, an XL type Gaming motherboard.
I thought I was going to set my neighborhood on fire the first time I cranked it up.
Here is an aside:
first time, I powered it on, luckily I had opened the case and I noticed liquid dripping from the Corsair pump. I then quickly shut it off, took it to FrozenCpu.com.
The guy who opened the PC was shocked, when he saw that it had 2 GTX 9800 GX2 and more in shock when he saw it had G1 Assassin motherboard with 24 gig of memory. He stared at me, and asked me "What are you trying to do with this build and why did I build it? My response was I build it with anger, I have not built a PC in ten years. He then smiled. Lucky we got a liquid cooling with longer pvc hose.
Enough of the specs.
On my Asus Windows server running MC , 23.0xxx, The AMD R9 gpu does not have much power compared to the Nvidia, yet buffering and audio issues were fixed by adjusting cpu and gpu ques in Madvr.
The PC is very quiet and the only software I have on this new PC is MC and it is going to have only MC.
PC via the cpu and gpu process the video one way or the other, when requests are made via the network, sends the info to the clients, in this case the Sony tvs, Samsung tvs etc.
My complain is not about the quality of the video, but the video and audio blending together.
In my first post regarding this issue, I asked if some one has experience configuring the Nvidia X server with the 340.102 driver. There are choices there. I wrote about Aliases etc. Someone with Nvidia knowledge, please help.
I think the card needs to be configured for it to work properly. I have not touched the setting, waiting for advice from forum members that are familiar with this type of hard ware.
Remember this is a Gaming mobo, designed for gaming, it should not have difficulty displaying 1080P videos over the network.
My network if not too slow, 100 down/10 up. and my wifi router is Netgear. The Asus has been set up for years and the 4 external libraries have been used to serve music and videos for almost three years on the Asus PC.
All tvs in the house connect to the Asus via the network wired. Only on rare occasion I actually would connect an HDMI to the server either to test and play with 3D offerings or just watch a new movie that is added to the library. Even Gizmo, Eos and JRemote can connect from anywhere to the Asus with no buffering 90%-95% of the time.
The point I am trying to clear up is this: During movie play back, there is buffering and that results in audio not being in syc with movie. Frames could be dropping when played over the network.
May be there is a memory leak some where, or something is broken in the chain. Something needs to be tweaked for it to play nicely over DLNA.
Please investigate these issues. One of the fun in this hobby is to be able to watch movies and play audio on the go without issues, assuming there are no network problems.
Thanks.
George.
Thanks.

I did a few days ago audio analysis of audio on videos.
I have tried two ways of watching movies.
1: I have a Samsung 40 incher 4k attached directly to the new server. Within Samsung there is a way to still use the smart hub to get to the "Contents", then pick a movie or concert of choice.
My test early A.M today was "Belle". It buffered right from the beginning to the end almost every two minutes displaying loading. When this happens, audio is messed up, at times screen tears.
Is this software not designed to be played over a server or DLNA? if so, it should play smoothly.
It is not playing smoothly.
Test 2: Upstairs, after upgrading to 23.0.28, I tried to load up " Car Wash", Celine Dion.. A new Day has come, Bee Gees One night only, Lionel Richie Live in Paris, all exhibited Audio not insych probably due to buffering.
Don't you think the cpu and gpu still needs to prepare the info and send the info through the pipeline?
We need to investigate why audio is breaking real bad at the Sony end. The Sony tvs 3 of them are connected to AIWA surround Sound processor via toslink.
The Samsung here connected to the new server via HDMI.
