External Graphic Card.

Hello.

I'm using a notebook with Yosemite and want to use two external displays at home.
To my sorry the notebook has just one HDMI output which I guess is very common.
It also provides 3 USB 3.0 Ports and so I'm looking forward to buy an external graphic card.

I couldn't find a lot of information for external graphic cards on a hackintosh.
I was thinking of a HIS Multi-View II [1] which is at least compatible with mac.

I don't care if it's HDMI or DVI (digital). I also could live with...
