I can't remember the last time I used Nvidia drivers with CentOS, but isn't that exactly what DKMS is for? I recall seeing Nvidia drivers recompile automatically using DKMS but I can't remember where :-(

Well, there is a surprising amount of cards that don't support 4k, especially the lower cost ones.
The issue with drivers is that the "built-in" X.org drivers that come in their open source packages have good support for older cards, but not always for the newer cards (which the 4k-capable ones will tend to be).
The X.org "nouveau" driver claims to support GeForce GTX 200 and 400, but doesn't mention the GTX 1050 chipset in the card you suggested.
Using Nvidia's own Linux drivers has usually involved downloading and installing kernel version-specific pre-compiled binary modules, which stop loading after a kernel update.
So, yes, due diligence because of trouble in the past.
I've just read up on elrepo.org, though, which seems to package up "kABI-tracking kmod drivers" which don't need to be recompiled for each
kernel update, and their repo includes nvidia drivers. So, that may be something to look into. Trouble is some of the stuff that turned up in my Google searches involved people struggling to get those elrepo drivers working, so it still won't be quite as simple and straightforward as it would be if I could get a 4k card that works with
the default X.org radeon or nouveau drivers.
So, advice from someone who has gotten 4k video working under X.org, with or without the elrepo drivers, would be appreciated.

Forgive my ignorance, but don't all current cards support 4K? And the
NVidia drivers would support that under Linux (<- assumption). For example, this card ($220 at ME) claims to support four 4K monitors (DP, HDMI, DVI-D): https://www.memoryexpress.com/Products/MX64640
Have you had trouble in the past, or is this just due diligence?

Hi. Does anyone on the list have experience and recommendationson
how to support a 4k monitor under Linux? We want to use a single Dell 27" 4k monitor (P2715Q) with a CentOS 7 system. What wouldbe
a good choice for a PCIe x16 video card, preferably with DisplayPort output, that can support 4k@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 begreat.
Unfortunately my Google searches this morning for this have had a pretty low signal to noise ratio. Mostly people having problems with nVidia drivers. Possibly relevant h/w info: ASUS M5A78L-Mlx+ motherboard and AMD FX-6350 CPU. Power supply has a spare 6-pin (3x2) PCI-E power connector for cards that require a dedicated power connection.
