Um... did they not realize that Matrox is still in business and bigger than ever?
They are huge in the custom GPU business for specialty video applications, and while they don't make a lot of desktop GPUs any longer, they are still have a few offerings that are helpful for people who need ultra high resolution displays (8-16K), or several displays (9+).
I used their G550 back in my first video editing rig, and tied it to a RT2500 as soon as I could afford it. I was so in love with the Parhelia card when it came out, but the 3D performance just wasn't high enough and non-linear editors were finally giving better AMD and nVidia, so I went with nVidia and never went back.
