I'm using 2xNEC 2690 screens and would like to also use my 2x LaCie 19" as well.
Now the options are get a better/faster/more memory graphics card for the big monitors and use the old one for the LaCies or get the same card to reduce chances of conflicts/bugs/issues.
If I get a different card, mixing brands would simply be asking for trouble would be my guess. ATI Radeon HD 2600 in at present.
Any have experience of this sort of set up?
