Hi guys! FInally my MacPro+Cinema Display arrived today, yet I have a small question regarding Windows. What is the best Windows operating system to fully take advantage of the MacPro processing power? I really need to be using Windows at least until January/February. The only software I use there is Rhinoceros and Maxwell Render. So I really need that the OS takes fully advantage of the 8 cores of the MacPro, to enhance my rendering speed! Which do you think is best for me, only to use Maxwell Render and Rhinoceros: Windows Vista or Windows XP?! And what version should I search for? Thank you very much for your help!
