[Fable PC] Playing off the wrong Video Card

I got fable and installed this afternoon. Upon startup it said that my video memory was insufficient to play the game. I figured it was just some error and the game would be fine, but as I got into the game I noticed it looked like total crap.

Thing is, Fable is running off of a Voodoo 3 (har har har) in my computer, and not my Radeon 9800 pro. I've got the voodoo 3 in there for my 2nd monitor because back when Vengeance was out, the game wouldnt start up when the 2nd monitor was connected, so I threw in the voodoo 3 and have the 2nd monitor running off of that so I'd have no problems.

I looked in the video options but there was pretty much nothing in there. Is there a way to change what card the game wants to run off of? Should I just disable the voodoo and put the 2nd monitor on the ati?


cliffs:
Bought Fable, Installed and started it up
Fable is running off of my 2nd video card (voodoo 3) instead of my primary card (9800 pro)
Need to find a way to change which card it runs off of

Windows XP Pro
AMD Athlon XP 2400+
ATI Radeon 9800 Pro [256mb]
Voodoo 3
1.5 gb of ram

take out that v3

or set the monitor connected to your ATI card as the primary monitor in the 'Display Properties' on the 'Settings' tab
