That seems to be a typical price for a gaming video card.
I mentioned earlier on, but probably should have been more clear, that
I'm not really interested in it for gaming. This is my everyday
desktop that I use for a Windows VM and office work. Hmm... are these
games on Linux that people are playing, anyway?
How about this card? It says it's on sale, but is it really?

This has three DisplayPort connectors - my current monitors do support
displayport, although I'll need new cables.
I did see one card online at the store I usually buy from. It's
a
Radeon™ Pro WX 2100 for $200CAD that supports up to 3 4K monitors. This
isn't a recommendation because I haven't done any research or
comparisons, but you might be able to find something.
Looks like about $140 USD on amazon here - but only 2GB RAM? Won't
that affect the maximum resolution?
