I want to know that whether XFX 9600GT Graphics Card(PV-T96G-YMFF) which is PCI-E 2.0 card, will fit in my mainborad(Intel Original DG35EC Motherboard) whose PCI-E version is 1.1. Is this PCI-E 2.0 card is backward compatible with PCI-E 1.1 slot of my mainboard ? If yes, what settings I have to do during installation for this backward compatibility? Should I connect PCI-E six pin power supply to the card when using it in PCI-E 1.1 Slot? Is this power connection to the card used only when fitting the card in PCI-E 2.0 Slot and not when fitting in PCI-E 1.1 slot?
