Opinion needed - 3d Max works faster on Vista or XP?

Hi everyone,

I just got my new laptop with 1 gig ram, with Vista installed, the first thing i tried is 3d Max, works good, but i still get some .dll error at start, but it still works, renders, etc…

in any case I think Vista is new and it has to be better, but i hear some things from people about the performance difference between xp and vista, that xp works faster or some people say vista is faster

What do you guys think, should i go and format everything and go back to XP?

or should i stay with Vista?

most important is 3d max, is it faster with vista or xp? i see that some things even load faster on vista, like the startup of windows is much faster on vista
