[LAU] Video card for audio (silent, low latency etc)

[Ben Bell]

Thanks to everyone for the tips and suggestions. I thought I'd write a
quick update to say it's all sorted now. tl;dr: Ryzen 3 with Vega works
just fine on 5.4.x series kernels.

I started shopping around for the cards Paul mentioned but couldn't find
versions with that chipset but without fans for the Radeon and the nVidia
route also turned up blanks.

Luckily, one of my machines is a work from home machine and I managed to
bag an nVidia Quadro K1200 from the stores at work. Four DP outputs and
it seems much more performant. That's the one with more monitors, but not
the low latency kernel.

The studio machine has a 4K display and couldn't use the nVidia drivers
because of the RT kernel patches. Turns out though that the solution was
staring me in the face: this is a Ryzen 3 motherboard and apparently has
built in graphics. It didn't work when I first built the machine but
upgrading to the latest kernel (5.4.x) all now seems good and the
performance is the best I've had from ardour, and that's running full
screen at 4K. I can scroll!

Anyway, seems that the Vega 8 (Ryzen built-in) graphics option is more
than adequate so if anyone reads this thread looking for answers, that's
another option.
