Gigabyte GV-RX18L256V-B X1800 XL
 

Performance was pretty good, as this card could play all the games we threw at it at 1024*768 with 4X AA and 16X ansio without a problem. Playing some other newer games (Age of Empires 3, etc.) provided a smooth frame rate at the settings I tried. In numbers this card, when not CPU limited was between 20% and 50% faster than the older x800XL mostly with AA turned on
