i'm using ATi Built card, definately go for it. else Asus is reliable as well, MSI started this season on ATi chips so I wont recommend them straight away.
as I had tested every manufacturer out of ATI chipset cards, powercolor use to make very nice cards, they started crap this season, else hercules was very nice , but they stopped manufacturing.
