Hi Keesw,
great topic!!
I have just bought a good machine, quad core, XP64(purely for the release of v13) 6gb of ram, & the speed difference between this computer & a similar computer but 32bit is not noticeable.
I was speaking with my local ArchiCAD reseller today & the only true benefits are for bigger (>4gb) projects. which are huge files!!! ie teamwork skyscrapers!
dont let the new marketing ploy fool you!
I have found xp64 is so limited in terms of drivers, applications etc (I cant even run itunes!!!!) that I have in fact found it more of a hindrance. I will be getting Windows 7 (64bit) asap.
Interested to hear others experiences with not only v13 on xp64. but xp64 in general.
also what / how window 7 is handling ArchiCAD 13.
