which Vista to get for AC12 & quad core

[Anonymous]

I am not going to be able to hold out for windows 7, looks like it
won't be out until June 2009 at best. I have to get Vista 64 bit in
order to have 4 or 8 Gb of ram, its required. but which version of
vista is best for AC12: business, OR ultimate? I have been told
that AC12 does not like 64 bit, is this true?

I'm using Vista Ultimate x64 with Q9550 and 8Gb DDR3. So far v12 is working nicely on it.

Hope that helps

Use Business. Ultimate is just Business with a bunch of stuff that you don't care about thrown in like extra eye-candy, games etc..

My system runs archicad noticeably faster in Vista x64 than it did in XP x64(about 10%-15% difference), and since SP1 Vista has been a lot better of a platform. I don't regret upgrading yet.
