Video card upgrade

[Shooter308]

I'm getting a Dell e1705 laptop with a ATI X1400 256MB video card in it. What do I need besides a Nvidia 7900 go video card to switch it over? I understand the card is easy enough to switch out, but do I need to just download nvidia drivers or do I have to flash the BIOS too?

Thanks,
Doug
