What would be a good choice for a PCIe x16 video card, preferably with DisplayPort output, that can support 4k at 60 Hz and has good driver support under X.org - hopefully without having to resort to 3rd party pre-compiled, version-specific binary kernel modules? If we can keep the price for the card below $200-$300 that would be great.

The short answer is... pretty much anything you can buy at this point
will do what you want, except for some of the older cards. 

I tend to stick to fanless cards, since the fans are always the first
thing to die, however there aren't all that many of them out there, and
they don't tend to support 4K but it varies widely. 

The AMD/ATI cards don't need precompiled 3rd party drivers, but that
doesn't mean they work better.  I haven't had much trouble with the
nVidia drivers... and if you don't need 3D performance, just use the
Nouveau driver which works fine for 2D. 

Regardless, a quick search on NewEgg reveals a handful of options that
fit your bill:

I have not checked each chipset against the latest CentOS X.org drivers
for compatibility, sorry.  That's one reason I actually prefer the
nVidia experience - they update faster than the AMD drivers.  (Usually. 
Except when they don't.  YMMV.)
