PC Stats has posted a review on the MSI RX1800XT-VT2D512E 512MB-Version RX1800XT Videocard

For hardcore gamers, there is no other component in a computer more important than the videocard. Equip a state of the art AMD Athlon64 FX-60 or Intel Pentium Extreme Edition based system with a low end videocard and framerates will still crawl along... On the flip side, a high end videocard can breathe new life into an aging system even, and at the moment one of ATi's best video processing units (VPU) is the Radeon X1800 XT. The MSI Radeon RX1800XT-VT2D512E videocard that is the focus of this review incorporates Radeon X1800 XT GPU and includes and extra 256MB memory above the standard amount, for a whopping 512MB GDDR3. The X1800 XT core hums along at 625 MHz, and the GDDR3 at a remarkable 1500MHz.
