Interesting note (imho), I went digging
around nvidia's site today, trying to familiarize myself with
their line of overpriced video cards aka quadro's. What I found
was most of their website doesn't render or work properly, half
the links were broken, half their pdf's didn't download, and in
general looks like something a 10 year old put together (or me,
meh for aesthetics). Wow, you'd think they could afford some
competent web developers at least.
Sadly seems every card that can do "mosaic" mode, including sli to
achieve nvidia's qualifications to support sli were $500+ used on
ebay, needing multiple cards of them, in the kepler (K) line of
cards or better to achieve. I guess it's one of those ymmv/"get
what you pay for" sort of things to support what I don't
necessarily expect should cost me $1000+ to support my 6 displays,
and really not sure even that is any better/worse than AMD's
support until I see it.
Seeing as no one at AMD gives a real darn about real linux support
(hark! yet another COD windoze game came out with broken dx
rendering, support!), it might be worth the price, but the
childish/broken website from nvidia makes me loathe to want to
invest there either, figuring I'll see the same brokenness I see
with amd.

Stephen, out of curiosity, what does your xrandr show
as a max framebuffer size on your quadro?
mb@host:~$ xrandr | grep maximum
Screen 0: minimum 320 x 200, current 11520 x 1200, maximum
16384 x 16384
This was a big limiter for me, in the past I couldn't
figure out why my old ATI 5800 card with 6 ports wouldn't
support a full, single framebuffer, but was internally
limited to 8192x8192, with the 6xxx+ supporting
16384x16384. Xorg wasn't too forthcoming with that info,
and it was prior to xrandr support in their drivers, so
totally left me scratching my head until escalating with
AMD support to an engineer with a clue that told me that.
With the advent of 4k displays, they still seem limited to
that, which means I can only do 4x wide until vendors give
to open that up.
Thanks!

Next time I have an absolute need to upgrade
hardware, I plan on avoiding ati/amd at all costs.
After dealing with them for a good 5 years as the only
real viable option to run my displays, only to be
wrought with constant disappointment, problems, and
frustration. Buying highly overpriced quadro cards
might be money well spent at this point, but I still
despise nvidia that they're really little other than
rebranded, and marked-up normal video cards with
driver-locked (to bios-id) features.
That said, going to set up some ebay agents to look for
decent quadro's to snipe. I had good luck getting my
last few amd cards that way on the cheap, gotta love
jbidwatcher for cheating some other person with a
last-second bid.
Thanks as always for the input Stephen.

I have
almost given up on ATI, if i want just multiple
screens i would look into the Quadro NVS cards. Such
as the NVS 510 or the K1200. They may be very
proprietary to get running, but my success with
Nvidia cards in both linux and windows really makes
it worthwhile. These cards will only do a single
monitor, but they are cheap enough to run 2 cards
with reasonable usability. or one NVS and one more
Gamer friendly card.
