Multi-display/ video card problems- 1st post

Hey everyone!

First off i just wanted to hi! This is my first post, and I hope i can give back to the CNET community- as i am some what tech savy.

Now the problem-
I loaded Windows Vista Ultimate on a separate partition in order to be able to run games on Direct X 10 i.e halo 2 (My main OS though is Windows xp Media center edition)
Something that i had not been aware of was that Vista SUCKS for multi-monitor support unless the GPU's run off the same Driver or are of the same type. Well, mine do not- am running Radeon 9250 & an NVIDIA 8800 GTS 640. The Radeon is mostly there for just for multi-monitor support- the 8800 i use for running the more hard core programs.

Now i have pretty much just given up hope for duel monitors on vista, which doesn't bother me much since i just planned to use vista for Direct X 10 support on games. But here is my problem.

- Every time i boot up Vista, it automatically boots the Radeon 9250, instead of the 8800- which it disables automatically (error 43).

so my question- How can i set Vista up so it boots the NVIDIA 8800 instead of the 9250? Keep in mind that if i remove the 9250 from the PCI slot, it WILL Boot to the 8800. (does this mean there is an order in boot sequence that i would have to alter in the Bios?)

One more question
* If i force a windows XP driver on the 8800 (To allow Multi-display support on vista) Will the card still run Direct X 10 or will it drop down to DX 9.c?

So here is a summary of my problems
* How can i set the NVIDIA 8800 as my primary GPU.
* Could i force an XP driver on the 8800 and still run Direct X 10?

Any comments or ideas are appricated-

and one more time- im happy to become a part of this community, and promise to help out the lesser n00bs.
