If you upgrade from Vista to Windows 7 you won't have to reinstall your games or drivers.

But an upgrade doesn't give you the streamlined clean system image that a fresh install would, and it may not perform quite as well.

In addition to smintal's post, from what I have been reading an upgrade can take a very long time depending on your current instalation, and some can take many hours.
If you take into account that W7, on a reasonably fast computer, as a gamer you probably have, the clean instalation will take less then 20 minutes, it may well be better and quicker to reinstall your software, rather then upgrade.
