I really want to ask a simple question with you guys. Why is my ati mobility radeon hd 5870 is not compatible GPUs? I had also seen the superiority list of the graphics card and mobility radeon hd 5870 is superior then lots of graphics card that are present on the list. I had also tried lots of tricks but nothing happen. I had tried to run the beta keys but it says that my graphics card is not supported by the Beta. SO I want to ask from you guys; What now I have to do for fixing the problem?
