As quoted from THG "Best Graphics Card for the Money - May 2010 (and before): "Don’t worry too much about which brand you choose, because all of the cards out there are close to Nvidia’s and ATI’s reference designs. Just pay attention to price, warranty, and the manufacturer’s reputation for honoring the warranty if something goes wrong.
That being said, I'm gettting (2) XFX Radeon HD 5770 1GB DDR5....XFX HD-577A-ZNFC
later this month/next month. I understand they offer a double life warranty. But I don't know what that is.....:)
