At first glance, ASUS’ Extreme X1800 XT TOP looks like no other Radeon X1800 XT card on the market. Sitting next to ATI’s own Radeon X1800 XT reference board, the ASUS Extreme X1800 XT TOP looks massive. It even looks large sitting next to a GeForce 7800 GTX 512MB. But actually, the board is based entirely on ATI’s reference board design for the Radeon X1800 XT. ASUS makes no changes to the board’s PCB — the dimensions of the PCB are the same and the card’s core components are indistinguishable. The sole difference lies in the Extreme X1800 XT TOP’s unique cooling.
