I have a Dell T3500 running Win7 Pro with ATI FirePro 2260, driver 8/17/2009, ver. 8.632.1.2000, with two Eizo CE240W monitors. Everything runs fine. I want to add a third CE240 monitor. Can I do it using this card? If not, what similar card do I need? I do graphic design: Photoshop, InDesign, Illustrator, etc.
