I've had my head buried in Nvidia for the last few years and have not kept up to speed on which Radeon card manufacturers are the most reliable and which should be avoided. For Nvidia I always go with EVGA or XFX. First look at the options for ATI, I see ASUS which I know is a quality parts maker, and Sapphire which I know has been making ATI cards for quite awhile. The rest though, Powercolor, HIS, Diamond, Gigabyte, MSI, VisionTek, I do not know anything about their reputation. If someone could illuminate me with their personnel experience, I would appreciate it.
