Thanks for helping, I did started researching since your first e-mail.
PNY, and also found ELSA boards (Gloria series) that use Quadro4 chips.
PNY 550 seems to have a splitter cable or something like that, since they claim its a dual output.
On the other hand, is hard to know that those cards are similar to Ti4600 which is quite cheaper.
Specially that we will need to import those cards if we need one, and the others are quite common in the market.
