    Just to explain to you, if you add in the PCI-E graphic card, the output will be only use that card (onboard graphic get disabled) , it is impossible to run both simultaneously at the same time.

    As far as i know no Optiplex system will run onboard graphics while a another graphics card is connected to the system - however the GX280 offers a special DVI adapter card which plugs into the PCI-E port. This is NOT a graphics card, it uses the onboard graphics chip to add an additional DVI port. If you used one of those then yes both the onboard VGA and this new DVI port would be active at the same time.  I've never done this but i would assume it's the same as a Dell docking station, which would also mean the port would be DVI-D - you could only connect a true DVI monitor, not a VGA with a DVI adapter

    no, you cannot, you have to choose between the extra agp graphics card or the internal onboard graphics.

    But you can add a 'dual head' agp graphics card, in this way you add 2 extra screen outputs. eg a Gforce FX5200

    If you just want to connect 2 screens, a dual-head will work fine, if you hope to create a killer game machine, the 3D result will not be good on an old GX280.

    note: for a GX280 you prolly need an older agp card, not a pci-e card.

    Lieven Embrechts received only 20 points because he said to use an AGP card, but the system uses PCI-e.

    I have a GX-280 in the office. Yes, it is PCI-E (NOT agp). Due to the bios settings, you can use either the onboard graphics or a PCI-E card, but not both. If you want multiple output, buy a card with dual output (or triple using an ATI 5xxx card). You can also buy a PCI graphcis card, and run both the PCI-E and PCI graphics cards to achieve 3-4 output displays.
