[Trisquel-users] External Graphics card for Laptop

[arielgnu]

So I had a Thinkpad X60 Tablet Laptop with libreboot :), and I new this from  
the beginning but the graphic card is not the greatest to play modern games  
like 0 a.d.

But then I found the following post somewhere in the Internet and I wondered:

Would it be possible to add an external graphic card through express card  
like in that post? If so, which card could I bought?

The only game I really want to play is 0 a.d. That game is awesome xD
