ATI Radeon X800XT Platinum Edition
 

"So you have weighed your options and you are deciding on the fastest ATI Radeon AGP videocard that money can buy. Even through there is plenty of X800XT standard edition available on the market, the Platinum Edition is only different because of its stock core and clock rates. The standard X800XT is clocked at 500Mhz core and 500Mhz memory but the Platinum Edition is stock clocked at 520Mhz core and 560Mhz memory."
