trust me thats not enough... xp needs at least 5 gig free to even be stable.. I was just hoping someone who has done the above would know a exact amount of space needed
steam itself is very tiny, so just above the minimum required by xp.
however, any GAMES you install will take up a lot of space. what steam games will you be installing?
It all depends on which games you installed with Steam. My Steam folder is 8GB and I left 10GB for Windoze. So I would say around 15-20GB depending on your games
