It was the 32bit version. For both Vista and 2008. Loaded Crysis on it also and its actually runs better then Vista. Should have tried it with everything turned off. With all the features loaded, it looks just like Vista. I also tried 2003 64bit, but it was slower than XP 32bit, buy about 200 points. That kind of supprised me. Must be the drivers, maybe something you should check out when going for the record.
