dom0 display adapter

[Gerard Lally <gerard.lally%gmail.com@localhost>]

Would someone kindly recommend a good middle-of-the-road PCI-express
video card for a NetBSD dom0 under xen 4.5.3 (pkgsrc-2016q2)? I'll be
working mostly on NetBSD, Slackware and Windows domU, but was thinking
of using mplayer on the dom0 for music and video. I'm assuming AMD is
the way to go? Would appreciate some advice before buying.
