[SOLVED] Need help with a PC that will include 2 GPU's(probably quadro) inorder to connect 8 monitors

[Nir223311]

Hello,my job is forex trading and i need 8 monitors connected to my pc simultaneously(for graphs)
ive been asking in my country for a PC build and i was given a build with the following main components:
I9 11900 2.5GHZ
MSI Z590 PRO WIFI
X2 pny nvidia quadro T600 4GB
SAMSUNG SSD 1T 980 M.2 NVME

after i got this reccomendation i asked another store in my country and showed them the build,
they told my that the PC WONT WORK, because the CPU support "20 maximum PCI LANES"
and each of the graphic cards requires 16 PCI LANES meaning that the cpu doesnt have enough pci lanes to support both gpu's
and they gave me a very expensive build that includes stuff like:
INTEL XEON SILVER 4314
SuperMICRO MB X12SPM-TF
X2 pny nvidia quadro T600 4GB
from what i understand its a SERVER and i see that the cpu has 64 max pci lanes
but this PC is incredibly expensive for me

can someone please help me understand and shed a light on this subject?i do not want to buy an expensive pc that wont work or wont provide me what i need
and this subject goes beyond my understanding in pc's

thank you very much in advanced!

You don't need 16 PCI lanes per GPU. That's what it would have been the best if you were gaming or using the full extent of a GPU butshowing graphs will not even come close to that.

You also don't need that good of a CPU (i9 11900). Almost any modern CPU which preferably would be from the 12th gen instead of the 11th, would suffice.

To be honest you might not even need a second GPU if you find one with 6+ outputs and then use the 2 from the integrated graphics.

EDIT: I also forgot to mention that if you have 1080p monitors then you can split a single DP to 4 monitors. I have read somewhere on how to do it and if you are interested I can search again to find it.

thank you very much for the answer
do i need to do anything in particular to make the 2 gpu's wprk together?
from what i understand both will just not work on 16 lanes each right? so they will work on 8 each? do i need to set that up somehow?
also just for general knowledge.can a gpu work on even less than 8 lanes?(if i were to put 4 gpus for example,not that i intend to)

and thanks for the suggestion about the integrated graphics! i havent thought about that.but i also not sure if im able to get a 6 outputs GPU
i havent really saw one honestly

Not exactly.
Card in PCI_E1 slot will work at x16 mode.
Card in PCI_E3 will work at x4 mode.

can a gpu work on even less than 8 lanes?(if i were to put 4 gpus for example,not that i intend to)

Graphics cards work just fine with less PCIE lanes than max. You get reduced PCIE bandwidth though.
For just connecting extra monitors this has no importance.

thank you
it is certain that the gpu can work on 4 lanes?someone told me that nvidia only gives guarentee for 8/8
also say i get a motherboard that support 8/8 or maybe this current one that support 16/4 do i need to setup anything or the manually set something for it to work certain way?
or it just sets itself automatically?

A GPU can work with 1 lane as well. The 8x/8x is when using SLI or Crossfire, again for gaming/ rendering, etc.
You do not need to setup anything. As long as the GPUs are recognized by the motherboard then all are setup automatically. Of course you will need to do the basic which is driver installation for the GPUs, chipset drivers, windows updates, etc which they are all part of a new system setup.

As for the 6+ output GPUs, I will edit this post in a while with some.
Btw, as I said in my first post, are you working with 1080p monitors?

thank you,i understand it better now
so the 8/8 work is through special interaction with SLI/CROSSFIRE?(which obviously i dont need)
i do use 8 full HD monitors 1080p yeah
would love to see what you saw about the splitting if its not a hard work for you dont wanna bother you
note that i use 8 monitors for 8 different graphs so i need to work to be "extended" and not to duplicate my monitors

The graphics cards will be independent, their job is to display relatively static images.
Only apps like fast action games actually need strong graphics cards.

Exactly what monitors are you looking at?
It occurs to me that one or two large 40" 4k monitors would do the job better.
Perhaps even a single 4k 55"tv like one of the LG OLED units.
That would allow you to size the charts and place them as you wish without borders.
Integrated graphics might be sufficient.

And, I second the thought that a 12th gen processor like a i5-12400 would be equally good and likely cheaper.
I5-12600K would be stronger than the 11900k.
If you now have a pc, run the cpu-z bench app and look at the single thread rating.
Here is what the I5-12600K can do:

I am sorry for the delay, I had some RL stuff going on. You can use something like this:
https://blog.tripplite.com/how-to-connect-a-single-displayport-signal-to-multiple-monitors

but what @geofelt suggested is also a very good idea. 2 big (40+inch) 4K TVs which you split each one in 4 equal parts (it's 1080p if you split it in 4). That way you have 8 graphs and you can do that with the integrated graphics only. Of course you need a CPU that has integrated graphics, which means NOT having the letter F for Intel (example: 12400 but NOT 12400F) and HAVING the letter G for AMD (example: 5600G and NOT 5600X).
