Is this a good way if installing a fresh copy of Vista?

I got a Dell a few weeks ago and I didn’t want to be left without all the right drivers etc so I just went with the install they put on it and took out all the bloatware.
Should I create a 2nd partition, and install a 2nd copy of Vista on that and then gradually migrate all the drivers and programs over to that side and then just eventually delete the first side?
Would that improve performance as well?
Then when Win 7 comes out I can just upgrade to that as well.
Anyway of knowing if I would get any conflicts or missing drivers or anything? Any problems you can think of?
Dell Studio 1555 btw
Answer #1
No, you are better of doing this:
1. go to the dell website and download all drivers for your computer
2. install a fresh vista by deleting the C partition
3. install vista
4. install drivers
5. have fun
Answer #2
better off, maybe
but I’d like to gradually migrate
