i live in the jodhpur city of country india.actually i'm buying a new radeon hd 7750.and in my country,the sapphire brand is known for its after sale services.but I've an asus service centre in my city jodhpur.So i'm confused between sapphire radeon hd 7750 or and asus radeon hd 7750.which one to buy ? I've read it on the site of asus that it is a widows 8 ready graphics card.is sapphire radeon hd 7750 not compatible with windows 8???i want to know this because I don't want to take any kind of risk with my graphic card whenever I want to upgrade to the windows 8.So which one should I buy from these two ?? Does asus graphic card has any kind of problems ?i was asking this because I've heard some horrible things about the asus graphics card that the became dead after few hours of installing or didn't ran at all.is buying the asus version of the radeon hd 7750 is risky ?? Should I buy a sapphire radeon hd 7750 ?please provide a good advice.
