Although Vista supposedly ships with thousands and thousands of drivers, if you're upgrading your self-built machine from XP to Vista, chances are there's going to be at least one component that has drivers not quite compatible with Microsoft's new OS. Instead of wasting hours googling like we did, head to RadarSync and grab the drivers there.
RadarSync is supposedly going to act as a Vista driver depository that makes it easy to find the drivers you want. We suspect something like this will be very useful for at least a couple of months until manufacturers get their acts together and update their drivers for legacy products to Vista.
