Hello, I have the M4A89GTD PRO/USB3 mother board and now have an ATI Radeon HD 5800 installed as well. The problem is I only have VGA monitors (2 of them) I am able to get one working using a DVI-VGA adapter, however the ATI Radeon HD 5800 only has one DVI port. And using a HDMI>DVI>VGA (2 adapters) fails. So I wanna be able to use my onboard grafix and my PCI GPU. Is this possible?
