I returning my 3rd card a nvidia BFG 7600 gs. I decided to try ATI some say they have bad drivers. The card I ordered is VGA DIAMOND AGP X1600AGP512SB I hope it works this time. I now see not having a PCIE slot really limits me. Some of the reviews I read people have a hard time installing the drivers. Anyone have some tips? Like should I clear the registry and if so how would I do that?
