I decided to put the GT9400 finally plugged with DVI dual-link in my lcd screen. But my screen has also a VGA port so as soon as i get a vgacable ill plug the IGP also. i can choose between four graphic boot-up settings in my bios.. PCI-E 16X , PCI-E , PCI , IGP. I chosed PCI-E 16X first and then IGP for booting . Now i only need to change the dvd burner for a SATA 2 to boost up the speed transfer.
By the way man I see in your system specs you wait for a decent cooling for your cpu..i got a 80mm fan here that wind up at 4850 RPM. Used but pulling air as hell. Many fins turbine look alike. I am in Quebec province if ever you are interested that could fit on a cooler that can take the 80mm fans. Cheap an I have paypal
