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?rr

Older cards have higher power and cooling requirements, and you have to factor in the cost
of adapters. Low end cards are being displaced by improved 'integrated' graphics and because
the vendors make more profits on higher end cards. In this market your best bet may be to look
for used cards from people who upgraded to newer gaming cards. Some older cards with 3 ports
[ HDMI | DP | DVI |VGA] may only support 2 monitors. If your system has the capacity (bus
slots and power), you might be better off adding another single-port card.
I have a low-end 10+ year-old Nvidia card and use nouveau, but a small mistake introduced after
kernel 5.8.18 wasn't corrected until 5.11 (just now being tested -- more recent changes may have
introduced new bugs that weren't detected since nobody could use them). Older cards are at risk
that open source drivers will not be properly maintained.
If you don't need high performance on all 3 monitors you might be able to add a USB3 card with
a USB3 to video adapter. There are adapters that have linux drivers, some reported to work
with Fedora using 3rd party RPM's.
