Hi all I'm upgrading from 32 bit xp to 64 bit vista, and was wondering how much performance improvement I will get, has anyone used both? Specifically one of the main reasons im upgrading is because it keeps crashing when Im trying to do paint effects hair, even though I've adjusted the paint fx settings to minimise the polygon count. And incidentally how do you think this setup will rate for working with maya (as far as run of the mill type desktop computers go) I will mostly be doing 5 minute or so animations. Maya 2008 vista business 64 bit Intel quad core 2.4ghz 8GB ddr2 667 quadro fx4500 Asus p5kc m/board Thanks Dave
