Re: Good GPU for OpenBSD build?

[Currell Berry]

Thanks for your response and link.  Apology for my ignorance about Xorg
drivers vs kernel drivers -- You are saying that the cards listed on the
nv(4) and radeon(4) pages do not necessarily correspond to what actually
will work, but instead just correspond to code that has been written in
X.org that may or may not have the accompanying kernel support in OpenBSD
to function, correct?

For "radeon" for instance I see a bunch of files at /sys/dev/pci/drm/radeon
-- I guess these files work in conjunction with the support in
MESA/Xenocara in folders like xenocara/lib/mesa/src/gallium/drivers/radeon
?  But perhaps for the nv(4) driver for instance there may or may not be
actual kernel support in OpenBSD?  Also if I were to plug in a card not
listed on any of those lists (a late-model video card for instance), do you
think graphics and multi-monitor support would work at all in general?  My
guess is that it would fall back to software rendering, but I don't know if
there's some sort of lowest-common standard that allows the 2d graphics to
work without acceleration somehow.

Thanks for any input.

Ok, thanks for the info.  I may opt for the Radeon HD6xxx card as I would
like to build with an AMD processor -- and I don't really need too much in
the way of fancy graphics, just the ability to drive multiple monitors
(which it looks like for example an HD6950 has) and watch youtube videos.

To save you the search for what the hell northern islands is:
the best graphics support you'll have is a Kaby Lake processor
without a graphics card. Failing that you want a high end
Radeon HD6xxx card (Northern Islands.) Skylake processors may
be the better option than those, thinking about it: the 6xxx
cards are pushing 10 years old now.

I believe this is easy to read: https://www.openbsd.org/amd64.html
Kernel drivers != X.org drivers
