I was wondering if its possible to get xp64 running on the 2008 mac pros; I searched and found a few threads for doing this on the previous generation but nothing on the current gen. I'm guessing that because vista 64 is officially supported now most people dont see the need but I couldn't get my software (Maxwell render) to properly work in vista 64 and I desperately need the extra memory. Everytime windows hits the ~3gb ram mark it just gives me the blue screen which is preventing me from getting the work I need done. Thanks in advance for any insight.
