Pcstats have made a reivew of the ATi Radeon X800 XL, here is a quote from the article :
In the high-end videocard market, the Radeon X800 XL VPU offers great value, perhaps that's why these cards are selling out everywhere. Today PCStats will be checking out this high-end value king in the form of the ATi Radeon X800 XL PCI Express videocard.
Backed by 256MB of GDDR3 memory, a 512MB version is available also, but the extra memory does little in terms of real world performance. Like all other videocards currently on the market, the Radeon X800 XL supports S-Video/Composite TV-out as well as component output for HDTV owners.
