So I finally ordered my Ram update and 64 bit OS. I got 8 gigs (2 gb x 4) and Windows Vista 64. Vista seems to have more driver support than xp 64, and it works generally quite well on my laptop. I like to turn off a lot of the graphical features.
Anyway will I need to download a 64 bit version zbrush or will the current one work with the new OS?
