I'm pretty sure you don't need vista to run the card. The card uses directx10, which is only in vista and not xp, but the card should be able to run in directx9 mode for xp. Anyway, the 8600GT that you posted is in the same boat at the 8400, its just a better card.
Have you tried putting the card in your computer yet? If you have and you're not getting a signal through it, you might have to disable the integrated graphics built into your motherboard.
To do this, go to start, control panel, system, hardware tab, device manager. In device manager go to the drop down box that says display adapters and right click your integrated graphics's and disable. Then restart your computer. Hopefully this helps!
