hello all, i have a question, i have a quadro fx 3400 and atm one 19 inch LCD and a 17 inch LCD, i'm looking into buying a 30" dell LCD and i would like to keep my 19 inch hooked up. Now i know the dell takes 2 ports and i can't drop the money for another quadro in SLI. So, can i add say , a 7900 gt (not SLI)? Would there be any driver issues? thanks for your help.
