Yesterday, Sapphire announced the release
of their next line in their Radeon series, the RADEON X1800XT Performance Edition. Essentially, the card is a reference X1800XT that comes stock overclocked, at a GPU clock rate of 700MHz, and a memory clock rate of 800MHz, making it one of the fastest cards on the market. The X1800XT alone has shown decent performance, and a stock overclocked version can add only more. The PE comes with 512MB of video memory, which though becoming more common is still pretty rare. More specific details such as pricing and availability dates have not yet been made available by Sapphire.
