Have you download the latest AMD display driver ~ ATI Catalyst Software Suite Version 9.3? No for me. AMD comes out a new ATI Catalyst Software Suite every month. And the naming conversion is based on year and month. For example, the current version 9.3, 9 == year and 3 == month. Normally, new features or performance improvement will be added on each display driver release. For ATI Catalyst Software Suite Version 9.3, the major feature is Windows 7 support and is a unified driver with Windows Vista. Besides, it also improves on Folding@Home (which I did not try at all for the moment). Windows Vista HDMI audio driver support
integrated into all ATI Catalyst 9.3 packages and new AMD Display Library (ADL) SDK. Finally, Lost Planet: Colonies gains up to 20% on 4800 series products.

Based on these features, I will skip this release. Looking forward for the next release that has 64 bit hardware support on ATI AVIVO Video Converter. Right now, it is still using CPU processing instead of GPU power. Luckily, I have a very powerful CPU ~ Intel Core2 Extreme quad-core processor QX9650.
