Have you considered replacing the two small monitors with a bigger,
higher resolution one? In some markets, the cost of a WQHD (2560x1440)
or UHD (3840x2160) IPS or AHVA panel has come down a lot recently.
With these high resolution panels, there is a problem with the size of
tools: for instance, I have a resolution of 1280x1024 and it is
sometimes difficult to catch the sliders of darktable tools, I fear that
it will be almost impossible to catch them with a higher resolution.
Once the devellopers will separate the display of the photos from the
tools to manipulate them (like in gimp), I would like to have the tools
on a screen with a reasonable resolution and the photos on another
screen with a higher resolution. But I am wondering if this possible
because, in that case, I need to be able to move the mouse from a screen
to another....
You don't mention what kind of panels you have or want, but as I'm sure
you know a good panel type is important for colour accuracy.
Another detail you don't mention is which driver you're using: the
vendor-supplied nvidia driver or nouveau. For the nvidia driver, try the
"nvidia-settings" application, as it provides much more control over
your displays and screens.

Yes, you can add another video card if you have a free PCI port on your
motherboard, but for the cost of a second video card and third monitor
(in both money, space and convenience) there may be better choices.
With a single good quality, high resolution monitor connected to an
adequate video card you can use an almost unlimited number of workspaces
to effectively have the whole screen available for as many applications
as you want.
The colour profiles are managed for each device. Look in "Color" in your
Settings and you should see each device capable of supporting a profile.
You will probably see that a profile has been automatically loaded.
