How much space do I need?

[NotAGolf]

I'm going to re-install vista on a new partition on my computer but i'm not sure how big I should make the partition. I have vista installed at the moment on a 25GB partition and it's using 21GB of this, but I was only using it temporararily to see if vista's actually any good and therefore only have a few things installed:
-MS Office
-MS Visual Studio 2005
-Winamp
-Nod32
-WinRAR
-BitComet
-MSN

I am impressed with vista so I want to move to it permanently but i'm unsure how much space to set aside. My guess would be 50-60GB? Is this about right? I will store music/videos on a seperate drive but all my games and other apps will be installed onto this partition. Any ideas?

Mines 30 gig, but thats only for programs and Vista. I use other drives for games/docs.
It depends on how many games you install really, since they take up a lot of room each.
