The Quest for 64-Bit Compatibility

All I want to do is build a completely 64-bit AMD dual-core box.

Oh, the many 64-bit options and the lack of details. You can buy a 64-bit box, but are the storage and network drivers 64-bit? Does my 64-bit PCI storage controller have 64-bit drivers? For Vista CTP 64-bit? When Solaris was the only 64-bit game in town (available to me anyway) I could get answers. Now that everyone is making motherboards that support Intel and AMD 64-bit processors, it gets much harder to track down answers

Hypothetical: Today, you need to buy a server to run Exchange 2003 Sp2 on W2k3 R2. You want to make sure it will run Exchange 12 with no bottlenecks that will hurt performance, like a 32-bit storage driver. What do you buy? Microsoft has tips for the folks writing drivers. Where’s the 64-bit hardware qualification list? Why is it easier to find Sun servers that meet Microsoft’s 64-bit HQL? This is close. But are all the drivers 64-bit? Vista? ATI has Vista drivers available.
