Best i/o break-out box for MC 8.5 to supply 3rd monitor, etc

I've recently up-graded from MC 5.5 to MC 8.5 and as a result my Matrox Mini doesn't work. And all the threads that I've found says that it is time to throw it away. 

Any suggestions as to replacement? What is the best PCI card i/o that will allow a third monitor for full screen, and some audio and video inputs/outputs?

Aja? Or?

And a second product question - has any manufacturer created a hub that has more than two thunderbolt inputs? Again I need to have a third monitor for full time, full screen, in this case from a lap top that has just one Thunderbolt port.

Thanks!
