Using a nVidia chipset for avoiding issues is kind of laughable considering their rather poor history in this regard (they've always performed well but ALL of their chipsets have had some issues except for potentially the most recent). Anyway, just disable the onboard graphics and you should be good to go.
What he said; I believe, and someone more knowledgeable can confirm, that you cannot have two different graphics card drivers installed on a Vista system. Thus if the onboard is of a different vendor or requires a different driver then you must disable it to use the discrete card.
As far as Nvidia chipsets go, I've sworn off of them. I owned an Nforce 3 board that had some issues before my previous 680i; after moving to P45 I don't think I'll ever go back. Intel chipsets just work too well, and the newer AMD/ATi chipsets for AMD boards are stellar.
