Hi!
I'm building a new machine and I'm looking at graphics cards right
now. I want a card that can handle 4k for regular productivity tasks
(if it can handle gaming at those resolutions doesn't matter), that
is as silent as possible and has good support in debian. Right now
I'm considering a Radeon RX 5700. Does anyone have any experience
with this card or a recommendation for another card?

Hi, I have four Radeon RX desktop GPUs (polaris10 and RX Vega) here
and they work very well, no proprietary driver required, just a recent
kernel and Debian.
polaris10, that's the 560-590 cards right?
What's the noise level like on those?
My RX570 is near silent, it's a design with two big fans that run slow.
The card doesn't overheat and doesn't draw too much power. It's very
capable for the price, it will output @ 4K, and run most games at HD
resolutions. Support is excellent, even compatibility with games
notoriously buggy is very good, my younger son runs Steam, Windows games
with Wine and whatnot and is very happy, me too.
RX580 is a different story entirely, runs hot and is power-hungry, so
not quiet. Dual fans design mitigates this but it ramps up the rpms very
quickly. Can output anything at any resolution up to 4K, can handle
games at HD or 2K resolution, even 4K with quality tuned down a little.
I wouldn't by this card now, I would go with a RX Vega56.
My Vega 56 and 64 are NOT quiet at all when loaded, they have a "blower"
design that makes a distinctive "whoosh" noise at the back of the
chassis. They also draw a lot of power. Performances differences are
marginal between the two, in my opinion Vega 56 makes a better option.
It comes on top regarding the price/performance ratio for high end
cards. Both are very stable though.
For Navi10 generation cards (RX5700) the support is still very green,
the firmware only made it to the official linux git tree a few days
ago [1]. You will need to ride with the latest kernel code (5.3
currently in development) and Mesa 19.2 (available in Debian
experimental only for now).
If you are not in a hurry wait a bit for those components to be
available in your Debian flavor (via backport, or if you are running
Testing/Unstable) and go for the RX5700.
If you want perfect support right now a Polaris10 or RX Vega card
would be a better bet. They can be had for a good price now and work
very well on Linux.
If you want support and the best performance it's the Radeon VII which
offers the best (pricey) option for now.
I want stability first and foremost, I just need the card to be good
enough to handle a larger monitor with a high resolution once I get
around to buying that, so I'm thinking perhaps the rx570 is a good bet.
Good bet and quite cheap now.
As for RX5700 support things look good, kernel 5.3.x is already stable
if you don't mind compiling it for now, and Mesa 19.2 is around the
corner. With the firmware now available from mainstream repository the
biggest obstacle has been lifted.
Given that you want stability I guess you are running Stable, maybe with
Backports, in which case RX5700 support may never happen during the
system lifespan. If you don't mind running Unstable or a "hybrid" system
and cherry picking or compiling packages you need, the support is
already fairly good. When Mesa 19.2 is released it will be in good shape.
Happy shopping.
For GPU support status on Linux the Phoronix website is the best
around [2].
Hope it helps.
It was very helpful, thank you.
