Here is the basic explanation for the failure of so many of the high powered machines you all posess...Vista 32 and 64 are having terrible trouble with games and gaming. SLI breaksdown and games not supported by Vista are immediatley crashed out. Many people have had these very same problems other videogames which are supported anyway. So really you should downgrade to XP because no matter how good your machine, the OS makes the difference!! Use XP throw awy your Vista
