It seems that Microsoft finally did it! ExtremeTech goes into detail in benchmarking the same system - first time after an Update, and second time after a Clean Install of Vista.
Surprisingly enough - it seems that an Upgrade does not slow down the system as it was widely know before with Windows XP.
Also, as they point out, this is by no means a recommendation to choose an upgrade over a clean installation, all they did was that they compared the two in terms of performance.
I would still suggest a clean install in any case if such is possible. It just makes things easier, and you finally get to install only the applications you really need. How many of you have a bunch of apps you just forget about and never get time to go and remove them? I know my system is breathing fresh air after a nice drive format :)
Head over to ExtremeTech for the complete article and benchmark results.
