I was wondering since I just converted to Windows 7 and had a question about graphics card and the BIOS. I should be getting my XFX 5770 and was wondering if when I install the card if I need to go into the BIOS and switch the display device over from the onboard to the PCI express or if Windows 7 automatically switches it over and uses the graphics card and disables the on board graphics. Please remember I am coming from XP.
