Running Vista on a medium PC, loving it.
The only thing that i miss is the Hardware profiles- Vista has so many services (around 60 ?) running in the background, and whilst i have disabled 20 or so that i never need, i still need 40 for every day use.
However, for gaming, i could cut it down to 10, but i have yet to find a way where i can stop certain services running for certain user accounts.
However, Vista is great, there was a lot of problems with drivers when it first came out, especialy from Nvidia, but most of these problems seem to be sorted now.
BTW... which version of vista did you get? If its Home Basic, there is no point in installing, it is shit
