Sorry for making the thread alive. But I couldn't skip saying the true things happening everywhere.
The XFX 460 GTX card that you saw and discussing about is true. But they are low grade cards made especially for underdeveloped countries like mine(Asia and Australia territories). Don't misunderstood me. I'm not blaming my country but the shopkeeper. They import this cards at low price but selling them at high prices like high grade cards and doesn't last more than 1 years. sometimes it gets spoiled within a month. Not only to the people around but also same happened to me also.
This goes for the other cards too. Hope you understand.
