Powercolor X1800GTO Video Card
 

The X1800 GTO cards use regular X1800XL chips with just 12 rasterizing pipelines instead of 16. Clocks are still at 500 MHz for both memory and core. We tested this card and found it is an overclocker's dream. Even though we could not unlock the extra pipelines, the card still overclocks very well, in our case to over 700 MHz on air cooling.
