The new Radeon 9800 XT is out. Reviews can be found many places. Some of the ones I enjoyed reading were here and here.

Been interested in hitting up some of that 64bit goodness, but have no idea about the advantages of the different chipset, well, AMDZone has you covered, even with a buyer's guide. Here is a Shuttle mobo to look at. And of course, if you are going to drop a chunk of change on a new mobo and processor, you might as well know how to tweak the BIOS JUST right for performance and stability.
