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.
