Radeon R7 and R5 can't drive UHD at all. You need Radeon R9 if you want
UHD... and R9 on Linux is a mess, so much so that AMD decided to throw
open the source doors to the world so that "we" can try to make it work.

Meanwhile on the Nouveau front, basic 2D acceleration with NV110
(Maxwell) GPUs is still listed as a "work in progress". KMS for example
does not work at all with NV110 cards. Much of the 3D work is finished,
though, but you don't need that for your editor and such.

The nVidia binary blob driver has its own collection of problems like
not working for KMS for all nVidia GPUs.

As for Intel, the absolute best you can get from Haswell is UHD at 30Hz.
The IGPs simply cannot drive UHD displays any better than that and
usually not even that well. Skylake can do it but that's because Intel
dedicated a lot of silicon to managing UHD output.

So no, "any card" simply *won't* be more than fast enough. Not by a long
shot.

As Mark said, it's an open source font. You can install it yourself.
